The current thresholds have been in place since the GST was introduced in 1991. The lowest threshold is, I believe, $350,000, which, for a new construction on a single-family detached home, makes it fairly irrelevant. There aren't any homes being built at that price point.
It's well overdue. We've been calling for those thresholds to be adjusted for longer than I've been around as part of the association. Our members, especially for the single-family detached, would love you to go a step further and maybe remove it altogether.
