Can anyone recommend a Canadian company to purchase a new convertible roof for a 69’ cutlass
Hello and Welcome to the Hagerty community! I checked around and we don't seem to have a recommended vendor in Canada for these parts, but you might want to check out RPM parts in Saskatoon as they seem to stock a lot of parts for your Cutlass! http://www.rpmparts.ca/Catalogs/Oldsmobile%20Cutlass.pdf
If they don't have it you might have to purchase from a vendor in the US. Best of luck!
