Not as well worn as the Aus ones but probably the same idea.
Funny thing is I would trust that local "MMF" government more than the official govt. They set this facility up to look after their own people because they know the federal/provincial healthcare system is a joke and kills people.
I get a kick out of destroying the population of Canada to get rid of 4 billion. Not even 40 million in Canada..
