So it seems that in Northern Canada 126.7 is the enroute frequency everywhere for everyone, and it works because of the low density of traffic and long distances between aerodromes.
I think I tried to explain to Dick, elsewhere, that his understanding and experience of the “MULTICOM” concept and conflation of the US and Canadian systems was a little superficial.
