I’m a Canadian like Goldfish, but I have heard of ACSM and NSCA, both of which are valid in Canada (if not as well-known as Canadian-based certs). That being said, to my knowledge, both of those organizations are fairly up-to-date and I would personally consider them over many other organizations. Bear in mind that every organization regardless will have their own biases and by-the-book rules that might conflict with realistic thought process.
