Top 10 Endangered Places 2025

Published with permission from the National Trust for Canada — Posted May 20, 2026

Every year, the National Trust for Canada publishes its Endangered Places List as part of its mission to bring people together to care for and promote heritage places.

The National Trust Endangered Places List is compiled from reports and news items the National Trust has been following throughout the year. First published in 2005, the National Trust Endangered Places List has become a powerful tool in the fight to make landmarks, not landfill. Anyone can nominate a site for being at risk and they offer a free toolkit to help you advocate for the places you love most.

The National Trust believes that heritage places are a catalyst for sustainable, livable, lovable communities, yet every year, more are lost due to factors like neglect, lack of funding, and weak legislation. By shining a spotlight on places at risk, the Endangered Places List raises awareness and bolsters the efforts of local heritage groups working to save them.
