People have been waiting for prices to go down in Toronto and Vancouver for a very long time. If it hasn't happened with the recent sharp rise in interest rates, I doubt it will happen when interest rates start to go down again soon.
That is also why a lot of people from there are moving to more affordable places elsewhere like here. If the high prices there were felt to be temporary, they would just wait it out.
Most people do have limits on what they can spend for housing and when prices exceed that, as they have in many places elsewhere in Canada, people end up making different choices (condo vs SFH, moving elsewhere, living with parents, etc ... ).
