Toronto tenants evicted from “unsafe” building with 24 hours notice City inspectors say the residential units were constructed without a permit By Julia Mastroianni Aaron Sousa/Unsplash A group of Toronto tenants say they were evicted with just 24 hours’ notice after a carbon monoxide detector in one unit went off and caused city inspectors to deem their building unsafe last week. The carbon monoxide detector installed by a resident at the four-unit apartment building above an auto repair shop at 1407-1409 Bloor West, went off around 1:30 am on March 10. Toronto Fire Services responded to a call for assistance along with city inspectors. Tenants returned to their units, thinking that the carbon monoxide issue had been resolved.
