From what I can find. In rare cases, it seems that you can only receive inpatient care in Canadian hospitals. I found this article which seems to cover the topic. From what I can gather, you may have to purchase a short-term insurance plan in current country you are residing in.
If travel to the U.S is an option. I would find a doctor there, and apply for a power chair there. Here's another article that breaks down the process. I hope this helps.

The short answer is no. Unlike Social Security benefits, which can be sent to you anywhere in the world, Medicare is only available in the United States.
You would need to go through the Canadian health care system to get your powered wheelchair if you wish to continue living in Canada. And I would caution about returning to the US if your only concern is getting a powered wheelchair because Medicare Part A doesn't cover that and Medicare Part B requires that you go through a rigorous process before being given a prescription for a powered wheelchair.
My best advice is to go visit a Canadian clinic and see what your options are.
