Do you know what cut of Kobe beef you had in Japan? Assuming budget is not an issue, your best bet will be to find the same cut in a Kobe Style or Wagyu beef. This is available in Canada. Get the same cut as whatever you had in Wagyu beef.
If you have no idea what cut it was, I'd probably start with a ribeye. It's one of the better, more popular cuts (also pricier). For example, Costco has Kobe Ribeye steaks generally. Note, they will be ridiculously expensive.
Stepping away from Kobe/Wagyu cows, look for a Prime grade Rib eye from a reputable butcher. What you're looking for is marbling as close to the following as possible:
Note, you likely won't get that marbling from anything other than a Kobe/Wagyu cow. That said, you can definitely find some good quality beef around Canada. I'd look for a good butcher (not in a grocery store) and start there.
