  • Tornadoes in Ontario 2017

    The 2017 tornado season got off to an early start on April 11 when an unexpected group of supercells developed along the lake breeze convergence zone north of Lake Erie. One of them spawned a brief, white cone tornado that snapped trees and power poles and damaged a barn near Thamesford.

  • Tornadoes in Ontario 2016

    The 2016 tornado season in Ontario was relatively quiet but not unremarkable. The season got off to an historic start when the province's earliest tornado on record touched down on March 16. It was an EF1 twister that struck northern Wellington County near Mount Forest, carving a path of damage through area farms. However, following this unusual Winter tornado the season ground to a halt, without a single tornado touching down in April, May or June. Finally, two weak tornadoes touched down on July 1st, breaking the dry spell briefly, and then no tornadoes occurred again until August 11. This landspout struck the community of Delaware, and was the first of five tornadoes that touched down during the month, an uptick in activity boosted the tornado count to near normal. By far the most notable and impactful event of the year occurred on August 24, when a pair of photogenic and damaging tornadoes struck the town of LaSalle and the nearby city of Windsor. The Windsor tornado was a high-end EF2 that damaged homes, destroyed factories and left four people injured. The final tornado of the year was an EF0 that touched down on September 10 near the town of Bloomfield in Prince Edward County.

  • Tornadoes in Ontario 2015

    The 2015 storm season got off to a slow start, and remained quiet throughout. As of mid-July, only a handful of low-end severe weather days had occurred, two of which produced tornadoes. The first confirmed tornado of 2015, struck between the communities of Thordale and Bryanston on May 30, damaging trees and tearing the roof off of a barn; the second caused minor damage near Holmesville on June 22. The most notable event of the season occurred on August 2, when an EF2 tornado damaged trees, barns and houses, one of them severely, on the north side of Teviotdale. This was one of four tornadoes to touch down this day, two of which were rated EF2. Later in the month, on August 19, an EF1 tore through forest in the Kapuskasing area. The final tornado of the 2015 storm season in Ontario occurred at Consiton, near Sudbury, on October 15. That tornado was a slender and photogenic elephant trunk that caused minor damage in the town, bringing to a close a relatively quiet season in the province.

  • Tornadoes in Ontario 2014

    Following the 2013 season which saw many tornadoes but little damage, 2014 got off to a destructive start. The first tornadoes of the season, an EF0 and an EF1, touched down in mid-May, one of which damaged trees, barns, and partially unroofed a house near Mildmay. Then, the following month, a high-end EF2 tornado tore through the town of Angus, damaging over a hundred houses, a number of which were destroyed. Early estimates placed the damage at over $25 million, making it the most damaging twister in the province since the Goderich tornado of 2011. A second tornado that day, a high-end EF1, caused extensive damage to a farm at Stroud. One week later, two more EF1 tornadoes damaged trees, barns and rural homes near the communities of New Tecumseth and Laurel Station. Four tornadoes touched down in July, including an EF1 at the end of the month near Grand Bend that produced considerable tree damage just south of town.

  • Tornadoes in Ontario 2013

    2013 was a notable year for tornadoes in Ontario for a number of reasons. The season started on April 18th, earlier than usual, when an EF1 tornado tore apart a large indoor riding arena near Shelburne, scattering debris for over a kilometer. This event was particularly significant for it was the first tornado in Canada to be rated using the Enhanced Fujita Scale. Two months later, on May 21st, three tornadoes touched down to the northwest and to the east of Lake Simcoe, with one at Glenarm rated EF2 - the season's strongest. That tornado damaged and destroyed barns, knocked down trees and power lines, and tore the roof and an exterior wall off of a house. Tornadoes in central and eastern areas of the province were the name of the game this year and, in terms of geographic distribution, made this tornado season unique. Not a single twister was documented in Southwest Ontario, the province and the country's most tornado-prone region. Indeed, every tornado recorded in 2013 occurred to the north and east of Wellington County... and there were a lot of tornadoes recorded! The season saw a total of eighteen confirmed tornadoes, considerably more than the yearly average of twelve. Five of these touched down on August 7th, in the largest outbreak since the record-setting nineteen tornado outbreak of 2009. The tornadoes on August 7th were extremely well-documented by both amateurs and chasers, uniquely photogenic for Ontario. Photogentic storms were unusually common in 2013 and, along with the higher-than-average number of twisters and lack of injuries or extensive damage, made the year a good one for storm chasers and enthusiasts in Ontario.

  • Tornadoes in Ontario 2012

    In contrast to the year before and the one that would follow, 2012 saw fewer tornadoes than average in Ontario and no particularly stand-out events. The two most notable tornadoes touched down at opposite ends of the season. The first occurred on May 22nd near Orono, to the east of Oshawa. The forecast this day was not calling for storms to be particularly severe and, indeed, the one that produced this twister was not. The Orono event was likely a lake breeze induced landspout rather than a supercellular tornado. However, it was especially photogenic for the province, a towering column of dirt and debris that looked like more like a scene out of South Dakota than out of South Central Ontario. The second interesting event occured on September 8th at Storms Corners in Eastern Ontario, when an F2 damaged farms and destroyed a trailer home.

  • Tornadoes in Ontario 2011

    A summary of the 2011 tornado season in Ontario simply must focus on the disasterous Goderich tornado. No F3 or greater tornado had touched down in the province since April 20th, 1996, when two of them tore paths from Arthur to Violet Hill, and from Williamsford to Blantyr. Ontario was overdue, and unfortunetely, that luck ended on the afternoon of August 21st in Goderich. On a day when severe weather was not even forecast, a truly remarkable storm developed in Michigan, becoming a powerful supercell that crossed Lake Huron on a direct course for Goderich. It came ashore seven minutes after Environment Canada issued a tornado warning for Huron County that included the town. First striking the Sifto Salt Mine on the shoreline, the tornado crippled that facility, killing a sixty year old man operating a crane at the site. It then tore directly through the heart of downtown Goderich, a kilometer-and-a-half wide wedge that devastated the town square, flipping cars and reducing historic buildings to rubble. The tornado then passed through residential sections of town causing extensive F2 and occasional F3 damage to homes. The event shocked Ontarians: damage totalled $150 million, thirty seven people were injured and one was killed. Sadly, the Goderich tornado of 2011 was amongst the worst in the history of the province. In a year that was otherwise average in most ways, the Goderich disaster made it one that will be talked about for generations to come.

  • Tornadoes in Ontario 2010

    Like the year before and the one that would follow, 2010 was an unusally damaging year for tornadoes in Ontario, thanks to two seperate events in June. In the early morning hours of June 5th, four tornadoes tore through Lambton County. Three of them touched down in the Harrow area, the strongest of which was an F2 that destroyed barns and greenhouses, shredded trees and knocked a house off of its foundation. Meanwhile, the most damaging tornado of the June 5th event was an F1 that ripped through the south end of Leamington, causing extensive damage in heavily populated residential areas. The tornadoes of June 5th caused over $100 million in damage. Less than three weeks later, another devastating tornado would touch down in the province, this time in the town of Midland, north of Barrie. The Midland tornado was one of two that day. Rated F2, it destroyed dozens of trailers at Smith's Camp Trailer Park and several businesses in an industrial section of town. Eight people suffered minor injuries and damage was placed at over $15 million.

  • Tornadoes in Ontario 2009

    After two relatively quiet storm seasons, 2009 was a truly remarkable year for tornadoes in Ontario. Tornadoes were more numerous, more damaging and more deadly than usual. Thirty five tornadoes touched down in all corners of the province, compared to the annual average of twelve. The season kicked off on April 25th with three tornadoes touching down in Winsdor, Guelph and Ottawa. Then, on June 25th, an unually strong landspout tornado, later rated F2, tore through rural areas to the south of Avon. Trees and power poles were knocked down, barns were damaged, and a house was destroyed, however a woman inside escaped without injury. In another exceptional event two weeks later, two tornadoes touched down in northwestern Ontario on July 9th. One large, long-track F2 tornado moved through forested areas between Lac Seaul and Ear Falls, hitting a fishing camp. Cabins were destroyed and three men - visitors from Oklahoma - were killed. This large and photogenic, well-documented and deadly Northern Ontario tornado was an unfortunate rarity. While this event alone would have made 2009 a year more notable than most, it was the tornado outbreak of August 20th that really made headlines. On that day, an incredible nineteen tornadoes touched down in South, Central and Eastern Ontario. The first of the day was one of the most damaging, an F2 tornado that moved from Ayton to Markdale. It tracked through the south side of the town of Durham, destroying homes and industrial buildings, then hit a conservation area east of town. There, several children were injured and one was killed. The tornado dissipated after producing F0 damage in Markdale, but its parent supercell went on to produce another F2 tornado in Blue Mountains. There, apple orchards, homes, ski chalets and the Georgian Peaks Ski Resort were severely damaged. As the system moved east and more storms developed, more tornadoes touched down north of Toronto, including F1s in Newmarket, Moonstone and Stayner. In addition, two of the most prolific tornadoes to strike the  Greater Toronto Area in recent memory tore through the city of Vaughan, damaging over six hundred homes, several of which were totally demolished. Each of these tornadoes was later rated F2, and were probably the most well-documented tornadoes ever in the province. Additonal tornadoes then struck the Haliburton and Kawartha areas, and in the Madawaska Valley. Tornado damage from August 20th was $150 million.

  • Tornadoes in Ontario 2008

    2008 was another below-average year for tornadoes in Ontario - arguably even less memorable than 2007. Only nine touched down and all were rated either F0 or F1. Of these, two events stand out as notable: the June 22nd Bryanston tornado and the July 27th Coboconk tornado. The tornado near Bryanston was highly visible and photogenic, widely documented in photos and videos. This was also true of the tornado at Coboconk; it was captured on tape by lakeside cottagers and residents of town. This tornado was the strongest of the season, rated as a high-end F1. It passed just to the north of town, touching down on Shadow Lake and then tracking several kilometers to the east. Swaths of trees were leveled, coming down and damaging a number of cottages. Three days later, an F0 tornado touched down near Hickson, the final event of an unremarkable season.

  • Tornadoes in Ontario 2007

    One of the quietest years for severe weather and tornadoes in Ontario in recent memory, 2007 was notable for how uneventful it was! The lone exception occurred on July 8th, when a supercell thunderstom developed over Lake Huron, came ashore to the south of Port Elgin, and then tracked for hours to the southeast toward Lake Ontario. The storm produced five tornadoes and hail as large as baseballs. The twisters were filmed by several storm chasers who compared the supercell to those of the American Midwest. This event would be talked about by Southern Ontario storm chasers for years to come. However, other than the exceptional, cyclical, tornado-producing supercell of July the 8th, the season was relatively inactive. The four other tornadoes were also weak, F0's and F1's, and were minor events in a slow and sunny storm season.

  • Tornadoes in Ontario 2006

    Until August 2nd, 2006 was turning out to be an average year for tornadoes in Ontario. The season kicked off when it ususally does, in mid-May, with a weak tornado confirmed in the Muskoka region. Throughout June and July, a total of seven weak tornadoes touched down on six occassions, all of which were rated either F0 or F1. Two of these touched down in the Newmarket area on July 17th, during a widespread severe wether event that saw wind damage occur throughout much of the province. Although numerous damage reports from that day initially indicated possible tornadoes, all of the damage other than that in the Newmarket area was confirmed as the result of straightline winds. Weeks later, on August 2nd, another system brought severe weather and damage to much of Eastern Ontario. However, this time tornadoes were responsible for much of the destruction which was also considerably more severe than the July 17th event. During the late afternoon and evening of August 2nd, a cluster of supercell thunderstorms developed over Eastern Ontario. Damage reports flooded in; tracts of forest were flattened, power lines were snapped and homes and cottages were damaged and destroyed. The most severe destruction took place in the town of Combermere where an F2 tornado caused devastating damage at the Opeongo Trail Resort, as well as to homes and cottages in the area. In addition, the town's Home Hardware had it's roof torn off. A second F2 tornado was confirmed to have struck near the town of Bancroft, where a house was destroyed. In the days, weeks and months that followed, Environment Canada confirmed fourteen additional F0 and F1 tornadoes from the August 2nd event. Until it was surpassed just three years later, these sixteen tornadoes made this the largest outbreak in Canadian history.

  • Tornadoes in Ontario 2005

    The first few months of the 2005 tornado season in Ontario were on the quiet side of average. The first tornado of the season touched down near Rodney on May 13th and was rated F0. Weak tornadoes - rated at F0s or F1 - then touched down on several days during the first half of June, but no tornadoes were confirmed in the month of July. It wasn't until August that activity picked up again with a few weak tornadoes confirmed early in the month. However, it was on the 19th when Ontario experienced it's most significant tornado event in years. On that day, two supercell thunderstorms initiated near the shores of Lake Huron and tracked all the way to the Greater Toronto Area and out over lake Ontario. The storms produced three tornadoes, including an F2 that travelled from north of Milverton to the east of Conestoga Lake, downing trees and destroying barns and cottages; the third was an F2 that knocked down tracts of forest, destroyed barns and outbuildings, and severely damaged a number of rural houses along its path. One more F1 tornado touched down in late September near Feversham and then, on November 9th when this damaging tornado season was seemingly over, a high-end F1 tornado tore through populated areas of Hamilton. The highly unusual late-season twister caused damage to dozens of houses, some severely, and tore portions of the roof off of Lawfield Elementary School, causing minor injuries to a few of the students inside.

  • Tornadoes in Ontario 2004

    2004 was a memorable year for tornadoes in Ontario and ushered in an active and damaging period over the next ten years. The outbreak of four tornadoes that occurred early in the season, on May 22nd, caused the most extensive damage the province had seen in years - though it would pale in comparison to several destructive years that would follow. The tornado at Mitchell ripped through the town causing considerable damage, while the one that struck Gads Hill only damaged one farm, but did so severely. That tornado tore the roof and some second storey walls off of a century-old victorian house, swept away a drive shed and barn, and uprooted, snapped and debarked every tree on the property. Rated a high-end F2, this was the strongest twister in Ontario since the two F3 tornadoes that hit the Arthur and Williamsford areas on April 20th, 1996. This tornado is often incorrectly noted in media reports and other lists as being rated F3.

  • Tornadoes in Ontario 2003

    The 2003 tornado season in Ontario was average in number but unremarkable in most other respects. Twelve tornadoes touched down, the first of which occurred on May the 1st, a probable F1 that caused minor damage at Tecumseth. Storm activity was then at a lull in the province until late June, when a few severe weather days resulted in three more weak tornadoes being confirmed in Central and Eastern Ontario. One of these was caught on video as it churned over Grindstone Lake but produced only minor damage when it reached the shore. Less than a week later, on July 4th, a strong F1 tornado caused extensive damage to forest in Northwest Ontario. In the middle of that month, four tornadoes again touched down in Cottage Country. Three of these occurred on the 11th, when low-topped supercell thunderstorms tracked across the Muskoka region. The season concluded with two weak tornadoes that struck at opposite ends of the province in late August, one at Florence in Southwest Ontario, and the other at Wolfe Lake in Eastern Ontario.

  • Tornadoes in Ontario 2002

    The 2002 season was one of the quietest in Ontario's recent memory; only four tornadoes were documented and, in an unusual occurrence, none touched down in southern parts of the province. The season kicked off at the end of May with a weak but photogenic F0 tornado in North Bay. June was quiet until the 23d, when an F2 tornado caused considerable damage at Fallowfield in Eastern Ontario. July was also inactive until the end of the month, but it was then that the most notable tornado of the year occurred. On the 28th, an F2 tornado tore through Halfway Lake Provincial Park, decimating swaths of forest and injuring four people camping there. Originally classified as a downburst, it was reclassified as a probable tornado based upon analysis of similar tornadic events that occured in Northern Ontario in subsequent years. Just a few days later, the final tornado of the season occurred at Kasshbog Lake, an F0 that brought the sleepy 2002 season to a close.

  • Tornadoes in Ontario 2001

    2001 was a relatively uneventful year for tornadoes in Ontario. The first tornado of the season struck Weissenburg at the end of May, and then none were documented in June, which is normally the province's peak month climatologically. The most notable day of the year occurred on July 4th, when four tornadoes touched down. All were weak, F0 or F1, but there were many photographs and videos taken during that event, particularly of the tornado at Campbellville which passed within sight of Mowhawk Raceway. Two more weak tornadoes occurred in the latter half of June, three in early to mid August, and then one more at the end of October. Looking back, the season was relatively average in terms of numbers but was lacking any truly impactful or memorable events.

    2000 was a fairly average year for tornadoes in Ontario, with 15 confirmed or probable touch downs, most of which were rated F0 or F1. The season began in early May, a month that turned out to be particularly active. Six tornadoes touched down in May, including two at the end of the month that were particularly noteworthy; on the 23d, a highly photogenic cone tornado struck near Appin and inflicted heavy damage at a pig farm, and the following day a damaging F1 tornado tore through residential sections of Gloucester. June was inactive with few severe weather days and no tornadoes occurring, but that changed in mid July when several tornadoes touched down, including a damaging F2 that tore through the city of Guelph. Two tornadoes touched down in the first half of August, with one on the 9th causing considerable damage to rural areas east of Windsor. The final tornado of the year struck on September 14th near Bolton, bringing the season to a close.

  • Tornadoes in Ontario 1999

    A total of sixteen confirmed or probable tornadoes touched down in 1999, making it an above-average and active season. The first tornadoes struck on June the 2nd; one hit the village of Purple Valley on the Bruce Peninsula and wreaked havoc at a farm, destroying buildings and tossing farm equipment, while the other touched down at Maple. Two more tornadoes struck in June, one on the 17th and the other on the 25th. July was particularly busy; six tornadoes occurred in the first week of the month, while another three touched down in the last week. The most damaging of these took place on July 3d, when an F2 caused path of destruction from Wodehouse to Duncan and Gibralter. On August 4th, two tornadoes touched down west of Toronto, including an F2 that struck portions of Flamborough and rural Burlington, and an F1 that hit a residential area of Hamilton Mountain. These were the most notable and final tornadoes of the season.

  • Tornadoes in Ontario 1998

    1998 was an average year for tornadoes in Ontario. A total of twelve confirmed and probable tornadoes touched down, the first occurring on May 31st and the last on the 25th of August. All of the season's tornadoes were weak, rated at either F0 or F1, and only one was particularly noteworthy. That tornado was one of four that occurred on June 2nd, tearing through Norwich. Dozens of houses were significantly damaged by the high-end F1; in addition, the local church had its steeple torn off and congregation hall destroyed, and trees and power poles were downed throughout the town. The Norwich tornado garnered a great deal of media attention for its direct and damaging impact on the small town, the only particularly memorable event of the 1998 tornado season.

  • Tornadoes in Ontario 1997

    Only eight tornadoes touched down in Ontario in 1997. The season began on June 17th and ended on September 6th, and all but one tornado were brief and weak. The exception was the tornado that travelled from Desboro to Williams Lake on the 15th of August, a damaging F2 that destroyed farm homes and swept away lakeside cottages. In an unfortunate coincidence, cottages on Williams Lake had sustained extensive damage the previous season when the Williamsford to Blantyr F3 passed across the lake. Without question, this was the standout event in an otherwise forgettable year for tornadoes in Ontario.

  • Tornadoes in Ontario 1996

    The 1996 storm season started with an historic event on April 20th as two powerful F3 tornadoes tore through parts of Grey-Bruce, Wellington and Dufferin Counties. Areas around the towns of Williamsford, Williams Lake, Blantyre, Arthur, Shelburne and Violet Hill suffered devastating damage. These photogenic twisters were perhaps the northernmost strong-violent tornadoes ever to occur so early in the season. They would also be Ontario's last F3 tornadoes for fifteen years, until the town of Goderich was hit in 2011. They made the 1996 season a truly unforgettable one, however the remainder of the season was fairly average in many ways. Including the April 20th tornadoes, a total of ten tornadoes struck areas of South-Central and Eastern Ontario during the spring and summer, all of which were rated F0 or F1.

  • Tornadoes in Ontario 1995

    Although only nine tornadoes touched down in 1995, the storm season will long be remembered by residents of Central Ontario's cottage country, which was ravaged by an intense derecho in the early morning hours of July 15th. The massive storm system knocked down thousands of trees, leaving some areas without power for weeks. Four tornadoes touched down during the event, including two F1 tornadoes that caused extensive damage at Balsam Lake and Kennisis Lake, and an F2 that devastated the town of Bridgenorth. Damage from the July 15th derecho was estimated to be in the tens of millions of dollars. Were it not for this event, the 1995 storm season would not have been a notable one; the five other tornadoes were all brief and rated at F0 or F1.

    1994 saw eleven tornadoes touch down in the province, with three of them occurring in Northwest Ontario. The most damaging of these occurred on June 30th when an F2 tornado tossed boats and blew apart cottages at the northern end of Lake of the Woods, just south of Kenora. All of the season's tornadoes occurred in June or July, with the exception of two that occurred in Eastern Ontario on August 4th. One of these caused F1 damage at Carp, before crossing the Ottawa River and ravaging the town of Aylmer, Quebec. There, dozens of houses were damaged and destroyed.

It touched down at Cache Bay on the 9th, causing destruction at a mobile home park and producing extensive F1 damage there. Two tornadoes touched down in August and two in September, the last of which occurred on the 9th, bringing to an end a relatively quiet tornado season in the province.

  • Tornadoes in Ontario 1990

    1990 would have been a relatively average tornado season in Ontario were it not for the F2 and F3 tornadoes that devastated the Komoka, Frome and Port Stanley areas of Elgin County on the 28th of August. The season started in mid-May when an F0 tornado occurred at Kushog lake, and then a handful of weak tornadoes hit various areas during June and July. The most damaging of these occurred at Lake Shebandowan, northwest of Thunder Bay, on July 17th. It was an F1 that destroyed forest and caused extensive structural damage to cottages. However, it was the late-season tornadoes that occurred on August 28th that make 1990 a year to remember. In particular, the hamlet of Frome was ravaged, with every house there either damaged or destroyed.

  • Tornadoes in Ontario 1986

    1986 was far less active than the devastating year that preceded it, however it too was one for the books. This was on account of three tornadoes that touched down on June 16, including two powerful F2s. One of them tore across the Haliburton and Algonquin Highlands for over 80km, damaging and destroying over 125 homes and cottages. Several lakes were struck and the loss of forest was tremendous. This was perhaps the most severe and damaging tornado ever to strike Ontario's Cottage Country. However, following this remarkable event, the season quieted down, with only two additional tornadoes touching down, each of them weak tornadoes that occurred in July, bringing to an end this short but memorable storm season.

The cataloguing of tornadoes in Ontario is a function of Environment Canada. In recent years, with the Tornadoes in Ontario Project, Environment Canada has undertaken the documentation of all known tornado events in the province, past and present. This has been the work of researcher David M. L. Sills, one of Canada’s preeminent severe weather scientists, along with Sarah J. Schriver and Patrick W. S. King. The information above is derived primarily from Environment Canada Special Weather Summaries and from official files and reports that are available in the archives at the Environment Canada Library, Downsview. To fill out the stories of these tornadoes, media accounts have been used to supplement that official data. Tornadoes classified as probable or confirmed are included herein.
