The Insurance Bureau of Canada says 62 per cent of all insurance losses from natural catastrophes in the country last year were in the province.
Claims totalled more than $730 million for damage caused by heavy rains, hail and wind, including from major storms that hit Calgary, Edmonton and southern Alberta.
Such storms have prompted some insurance companies to double the deductible for weather-related claims this year.
There was also record hail damage to crops last year. Alberta Crown corporations paid out more than $451 million in hail insurance to farmers.
The insurance bureau says extreme weather is on the rise across Canada.
