Numerous adhesives and construction supplies (too many to list), everything from light fixtures to patio decorations and furniture that are made of plastic that goes brittle in the cold. We just had to replace several outdoor light fixtures because they weren't properly weather sealed and snow melt and rain got inside and ruined the internals with water damage and mold. My grandparents have gone through several shovels and snowblowers because they seemingly don't make them sturdy enough to handle anything more substantial than a light dusting of snow.

Just a few examples off the top of my head. Some of it is down to the general poor quality of modern products for sure, but it doesn't help that things just aren't made for life here where it can get to -30c and lower.
