My experience (I’m a hiring manager) is that a LARGE number of big US-based tech companies are only hiring in Canada right now for pretty obvious reasons, and are competing aggressively for top talent here. Many companies are backfilling American roles with remote Canadians when someone in the US exits right now. It’s the best I’ve seen in the ten years I’ve been here.
This is a candle in the dark, thanks for sharing. Hopefully this has residual effects outside tech, for my spouse's sake and that of many others, but it's good nonetheless.
