Severe weather led to $2.1 billion in insured damages in 2021, making it the sixth costliest year in Canada's history, says the Insurance Bureau of Canada (IBC). In tallying the cost, the national insurance organization said climate change is already showing just how expensive a world-dominated catastrophe will be. Last year, the most expensive single event occurred in November when an atmospheric river triggered widespread flooding across southern British Columbia and led to $515 million in claims.
