Insurers across Alberta and Saskatchewan are bracing for a new round of claims after a prolonged severe weather system delivered record-breaking rainfall across central Alberta over the weekend and brought tornado watches to large parts of Saskatchewan, adding further pressure to a Prairie market already absorbing hundreds of millions of dollars in losses this season.
Edmonton has officially recorded the wettest June in the city's history, with 244 millimeters of rain logged as of June 27, surpassing the previous all-time June record of 216.5 millimeters set in 1914. A rainfall warning remained in effect through Monday, with an additional 70 to 80 millimeters forecast for parts of Alberta. The system stalled over the province due to a Rex block, a high-pressure pattern that acts as a traffic jam in the atmosphere and produces prolonged rainfall and elevated flood risk.
The flooding forced road closures in Edmonton, with westbound lanes of Yellowhead Trail shut at 170 Street on Saturday. In Tofield, southeast of Edmonton, an overland flooding emergency was declared and Canada Day festivities were cancelled. Emergency alerts were issued across multiple Edmonton-area communities after heavy rainfall pushed the region's stormwater systems to capacity, with localized flooding and sewer backups reported in neighbouring communities.
In Saskatchewan, tornado watches and severe thunderstorm warnings were in effect across wide areas of the province on Saturday, covering communities near Estevan and Weyburn as well as Regina, Moose Jaw and surrounding areas. Environment Canada warned that conditions were favorable for tornadoes, large hail, strong winds and heavy rain. The threat diminished Saturday evening, though parts of Alberta are expected to continue seeing rain into this week.
The weekend events come at a point in the season when Prairie insurers are already under significant strain. Saskatchewan Government Insurance reported more than 10,000 auto claims and 800 property claims following the June 9 Regina hailstorm alone, with preliminary damage estimates approaching $80 million. SGI brought in additional staff, extended working hours and scheduled weekend appraisal events to manage the backlog.
Earlier in June, an EF3 tornado near Oxbow, Saskatchewan caused significant structural damage to homes and farm buildings, and six tornadoes were confirmed across Alberta's Peace region in a single week.
Aaron Sutherland, vice-president, Pacific and Western, at the Insurance Bureau of Canada, said this month that it had been "an active start to the severe weather season in Western Canada, with flooding in Alberta, Saskatchewan and Manitoba, damaging wind gusts and hail in southern Alberta and wildfires in British Columbia."
Overland flooding sits at the center of the Alberta claims picture, and coverage for it is not automatic. Standard home insurance policies in Alberta do not include overland flood protection as a default. It must be purchased as a separate add-on, and even then is not universally available to high-risk properties. Policyholders affected by the current flooding should verify whether their policies include overland flooding and sewer backup coverage before filing claims.
Statistics Canada data released this month showed Alberta home insurance premiums increased 391.6% between 2005 and 2025, the steepest rise of any province, with a 55.8% increase in just the past five years. The IBC has linked the trend directly to extreme weather, with Alberta accounting for a disproportionate share of national catastrophe losses.
Formal insured loss estimates for the weekend events are not yet available.
