Iphone 15 pro max

Highly doubtful. All current iPhone 15 model iPhone's sold in the US are dual eSim only. If you want to buy a Canadian model iPhone, you need to buy it in Canada. Conversely, you cannot buy a US Spec iPhone 15 model in Canada.

You would need to buy it in Canada. Unfortunately that is your only option (if you can’t go there but know someone who will or lives there you can get them to do it for you).

Try contacting an Apple Store in the USA and ask them if they have it in stock (also in terms of color, capacity).

iPhone 15 ProMax model code (manufactured for Canadian market) is A3105.
