If anything, CSA was more strict than UL up to the 70's when I was in charge or getting things done for a small technical firm that used contractors to produce some electrical products used by dental technicians. Of course it got complicated with some stuff made in Japan, etc... Always a specimen had to be provided, and always some recommendations or required remediation was returned, often never the specimen was returned. Once blessed a design was/is blessed forever. Now you know.
