Only one Eastern spot in canada with enough home-car support...QuebecIIRC it has to do with getting tools and products into Canada.
I too would have liked for Canada to host a national meet .... that's why the meet was named North America Solstice Sky Meet (since changed to NASSAM)
like Mt. Tremblant
BUT...(caveat) Tremblant is not just for skiing.....very touristy in the summer in the Laurentians
and even with exchange rate over 30%....$300. a night will deter a lot of people
and Mom is right...no US vendors will come due to border/import restrictions
