Montreal reassesses basement apartment viability due to flood damage from Tropical Storm Debby, Quebec's costliest weather event ($2.5B).

Following severe flooding from Tropical Storm Debby, Montreal officials and insurers are reassessing the viability of basement apartments. The Insurance Bureau of Canada reported this flooding as Quebec's costliest weather event, causing $2.5 billion in damages. As extreme rainfall becomes more frequent, some insurers are limiting flood coverage. Experts advocate for infrastructure updates and natural solutions, but concerns grow about housing shortages if basement living is restricted.
