I have not applied because of the border closure yet. I have insurance in the states, Medicare, and I was planning to go back and forth across the border for treatments until I can get Canadian Health. However, the border closure is complicating things as my wife is Canadian and might not be able to get through on the US side and I as American may not get through on the Canadian side. We just bought a home in BC and sold our home in America. We will be homeless soon so this is getting critical.
If you haven’t even applied for spousal sponsorship it may be 6-12 months before you even qualify to apply for oHIP and start the 3 month wait times. Without being a resident of that state don’t think you would qualify for Medicare.
