You missed my point, Canadian medical insurance will only pay up to the amount paid in each respective province, and that is significantly below US costs. What I was talking about is that each province has set limits to which you are allowed to be out of province in any given year. So, in NS we can be away for up to 7 months, for example that means if you spend 3 months in Mexico, one month in the US, and you want to go to work in Alberta, you only have 3 months left, or your MSI will reject any claim, even though you are only out of country 4 months.
I know lots of people who go west to work and just ignore it, and don't get caught, but if you do, you end up with no coverage.
