No, that’s not the reason. There are residency requirements, but the coverage is portable and universal between provinces.
If I pull up stakes and move from Saskatchewan to Alberta, yes, there’s a three month residency requirement before I get an Alberta health card.
But that doesn’t mean I pay for health care myself. During that three month period, my Saskatchewan health card covers me for medical care in Alberta.
Alberta then bills Saskatchewan for my medical care during the transition period.
So no, the waiting period doesn’t deter people from moving to another province.
The real reason that portability doesn’t bankrupt our Medicare system is pointed out by Dangerosa and Leaffan: there isn’t a great deal of difference between the providences … er, provinces, in the medical coverage. They’re all subject to the Canada Health Act rules, and generally provide the same level of service.
If a treatment is available in Province A that is not available in Province B, and a resident of Province B needs that treatment, the Medicare system in Province B generally pays for that person to get that treatment in Province A.
This issue normally comes up with the smaller provinces/territories, like Prince Edward Island and Nunavut. Given their population, they just can’t cover the full range of medical services that larger provinces can cover. So the medicare systems in the smaller provinces and territories will pay for their residents to get that health care.
For example, it came out in the trial of Senator Mike Duffy that he was concerned that if he kept his PEI residence, as required by the Constitution to be a Senator, that PEI hospitals couldn’t treat his particular heart condition. But the PEI Medicare system made an arrangement for him to get the treatment he needed in Toronto, paid for by PEI.
Another PEI example is that there are no doctors in PEI who perform abortions. But abortion is a medical service and therefore covered by Medicare. The PEI medicare system therefore pays PEI residents who want an abortion to have it done in the neighbouring province of New Brunswick.
