Where can I buy "Canned Oxygen" in Canada?!

Best Answer - Chosen by Voters

do you mean "canned" or do you mean high pressure bottles?

If the latter look in Yellow Pages and call up a few distributors. If it's for medical use ask when you next see your doctor. You can bet that they will ask what you want it for even though it's not a controlled substance. Try a welding supplies store, they will probably have smaller bottles for transportable gas welding and cutting.

For goodness sake do a safety course before you even think of taking delivery, it's dangerous stuff, much more so than compressed air. You'll also need a set of valves and regulators.
