Will your health insurance coverage here in Qatar cover you when you visit Canada? (I'm assuming that you will go home for vacations annually)

If not, will you be able to avail of Alberta health care services when you are in Canada? Most provinces restrict non-resident's coverage for a certain number of months after they arrive back in Canada - some provinces are as short as 3 months, others 6 months. Check it out.

I believe most provinicial health care providers consider you to be non-resident for health care coverage if you reside outside of Canada more than 181 days per calendar year - but I stand to be corrected on that point.
