Report – The Impact of Catastrophic Flooding on Canada’s Housing Market:

The Intact Centre on Climate Adaptation publish a report on February 15, 2022, which investigates the impact of catastrophic flooding on Canada’ housing market. No shared priority will unite Canadians from coast-to-coast more than protecting their homes, owned or rented, from flooding. As this study quantified for the first time, flooding in Canadian communities compromises the residential real estate market in three material ways: (a) lower average sold price of houses, (b) increase in average number of days on market to sell a house, and (c) reduction in average number of houses listed on market.

“The findings of this report do not surprise me” said Gary Will of Will Davidson LLP. “They underscore the impact on housing prices and the need to actively reduce flood risk through updated flood plain modelling and mapping, and to re-think development, without delay, as flooding affects everyone from planners, home owners to government decision-makers.”
