Short answer
Yes, when the mark is the Canadian one. Intertek's ETL mark with a small 'c' (cETLus, or ETL with 'C' beside it) means the product was certified to Canadian standards by a certification body accredited by the Standards Council of Canada, the same standing as CSA or cUL. An ETL mark with only 'us' covers the United States and is not a Canadian approval.
Canada does not require one particular brand of mark. What your provincial electrical or gas safety authority accepts is certification to the Canadian standard by an accredited body, and CSA, UL (cUL) and Intertek (cETLus) are all such bodies for commercial kitchen equipment.
Check the data plate or the maker's listing rather than the box or a sales page. A unit with a US-only listing may need a field evaluation or special inspection before it can be connected, which adds cost and delay.
Sanitation is a separate mark. NSF (or an equivalent food equipment listing) covers how the food-contact surfaces are built and cleaned, and many health inspectors look for it in addition to the electrical or gas mark.
