I live North of 60, in Whitehorse in the Yukon. With about 35,000
inhabitants, We are the largest Canadian city in the North.
Here, we could get Starlink for a while. But last year, they introduced
a waiting list. There is no more capacity to go around.
I assume this will remain so for a couple more years, until we get new
satellites.
In other parts of the Yukon, I am not aware of waiting lists.
Cheers
