@ElsieD Also poke around on various sites under different brand names for just "stainless baking sheets" or "stainless baking tray" — these seem to be a generic import from China, and at least on US Amazon, you can find *identical* pans under a dozen brands. I bought some larger pans of a similar style recently for my weird size wall oven, and ended up with "HUSHIDA" instead of "TeamFar." Every detail of the pans appears identical.
The selection seems to be less on amazon.ca but there are a few -- e.g., this "Raynag" pan for $18: hopefully eGullet-friendly amazon.ca link
