I hadn't heard the phrase "shard yard" until reading it here (this post from Winnipegger on Facebook). I guess Guildwood Inn could be a shard yard, here in Scarborough, Ontario. What a great place for urban explorers to try to find and photograph! I'll be looking for shard yards online. They could include remnants from cemeteries as well as demolished buildings.
The remnants of important buildings demolished 40 years ago may see new life following Monday’s approval of a transfer of stewardship to Heritage Winnipeg.The city’s downtown development committee voted in favour of declaring as surplus historical “shards,” or pieces of building construction materials and artwork, and transferring responsibility for them to Heritage Winnipeg.Cindy Tugwell, the group’s executive director, said this plan is a result of two or three years of work between the City of Winnipeg and Heritage Winnipeg.
