I have sorted all the .ca's available on Flippa with the highest priced ones first.
One would assume those are the best domains but you need to judge that for yourself.
Seems like Wade Smith is listing most of the good .ca's on Flippa. I checked the recently sold .ca's and there were none. The only big .ca domain I recall selling on Flippa is Rate.ca for @$75k in 2019/2020
