Dental care, housing deals with cities and the fall back carbon pricing were all done dispite provincial pushback (as far as I’m aware).
The only one where they worked with the provinces was the daycare, and that took like 18 months for provinces to actually agree on and even today provinces like Ontario continue to drag their feet on.
From what I’ve seen over the last 3-5 years, the provinces have very little interest in actively working constructively with the feds.
I don’t know what the current status of the healthcare chats are, but a few years ago the feds were willing to help push additional funding into the provincial healthcare systems, but the provinces needed to agree to terms (I believe the terms were around the money needing to be spent on the public healthcare system and not working towards privatization). as far as I know the talks never went anywhere, and healthcare systems are still underfunded.
Any one who assumes that another party is going to blanket support a non-confidence vote doesn’t understand how minority governments work.
These are times when other parties have the leverage to influence what bills are being passed.
If things got bad enough that no other parties agreed with direction then ya we would be heading to vote, but realistically things aren’t that bad right now, they could always be better, but it’s not bad enough to just throw away leverage.
