Ok but they’re not in their home province. They’re working in Alberta. Going to the doctor in the province you’re living and working in, even temporarily, isn’t a scam. What would you have them do, hop on a plane to a different province to access primary care?
If Alberta has chosen to open the doors to out of province workers, it has to be expected that that will increase demand on certain services. Failure to adequately resource those services is not the fault of the service users, which Alberta and its industries sought to attract to the province in the first place.
So yeah, you described it as a ‘scam’, but it isn’t at all that.
