Personally speaking I don’t think it’s suppose impact prices much. In fact they were so concerned about it they started adding in exemptions almost right afterwards.
In itself there is a lot of Canadian wealth tied to housing so unless there’s some magical situation where affordability happens in a vacuum people will fight hard to against any policy that hits their wallets. My proof for this is that in 2021 when we had a election 80% of people decided that having the two parties that brought us through decades of housing costs going up was who they wanted to run the country.
