Is Amazon Canada worse than Amazon USA?

It depends on what you mean by “worse.”

In general, Amazon.com (USA) tends to have the larger selection, especially for niche items and third-party marketplace listings. It also often has more competition among sellers, which can mean better base prices on some items.

Amazon.ca (Canada) is often more convenient for shoppers in Canada because you may avoid or reduce cross-border shipping costs, import fees, currency conversion hassles, and longer delivery times. For many Canadian buyers, that convenience can outweigh the smaller catalog.

So a fair summary is: Amazon.com is often better for selection and sometimes price, while Amazon.ca is often better for convenience in Canada. Pricing and availability change frequently, so it’s worth comparing both sites for the specific item.
