Those who love Toronto's heritage could only watch in horror as demolition began on four buildings, known as the Dominion Foundry, this week. The four abandoned buildings at 153 to 185 Eastern Ave. in Corktown were once part of a thriving industrial enclave along the lower Don River. The foundry site "contains the largest concentration of heritage buildings to be preserved within the 80 acre West Don Lands precinct," according to the City of Toronto. The building at 153 Eastern Ave. was the foundry building.
