| Comments | On November 15th, a strong frontal system passed through Ontario and Quebec. The system brought an array of hazardous weather conditions: An EF1 tornado touched down near Georgetown; there were four confirmed downbursts events (Dunnville, New Dundee, Ingersoll, Port Burwell) with wind speeds ranging from 115-135 km/hr; strong winds across much of northeastern and southern Ontario (Port Colborne, for example, recorded maximum wind speeds of 132 km/hr with 10 consecutive hours of winds over 80 km/hr); and a significant seiche in Lake Erie (4 m sea level difference between Toledo, Ohio, and Buffalo, New York). As a result, this system generated widespread damage across Ontario and into Quebec - southwestern Ontario was the most impacted. By the early evening of November 15th, over 1 million individuals were without power in Ontario, Quebec, and the United States. Hydro One reported over 542,000 customers that were affected and over 500 downed hydro poles; power was still not fully restored to all customers by November 19th. Power outages were also reported in Quebec. This event is estimated to have cost $87 million (2020 CAD) in insured losses. |
