Is There An Apple Credit Card For Canadians?

Apple doesn't offer credit cards in any country. Whether there's a general credit card for Canada that has as a reward credit toward iTunes purchases I'm not sure, but doing a web search I can't find one. Cards that offer such "rewards" often pay for them by having higher interest rates, fees, etc. so often they're not worth it.

The Juniper card with iTunes rewards offered by Apple does not seem to be available in Canada.

I should have said that Apple themselves don't offer a credit card. They do partner with Juniper in the US, as Chris said, but that card doesn't appear to be available in Canada. Others have reported that Juniper's terms, rates and fees are poor, so again, it probably wouldn't be worth it even if it were available. Shop for the card that gives you the best deal and ignore "rewards" unless you compare terms very carefully. The only feature of a credit card that's usually of much use is an automatic extended warranty on gear you purchase using the card.
