Remember that many (most?) people coming from Canada go thru US immigration there, so these numbers (from US airports) likely represent non-Canadian visitors.
With so many fewer people coming the ratio of fliers to immigration people is going to be lower, chance of getting hassled is going to be that much higher.
Personally I'm unlikely to return while these stories of bad things happening to people at the border continue
(this isn't a new thing, in particular because the US has no exit processing infrastructure - people get tagged as overstaying even though they've left, get popped into detention when they return - always keep your boarding passes when you leave).
