Just so you know, the CEO of the Canadian Home Builders' Association, Kevin Lee, said that the Conservative plan “will help improve affordability and enable more supply.” I'd say that's self-serving, as it's the Canadian Home Builders' Association, but Mike Moffatt, who is a housing economist often referred to by the current government, said, “I admire the boldness [of such a move]. This will get more housing built.” That's not too biased, probably. Tim Richter, who heads up the Canadian Alliance to End Homelessness, called this tax cut “smart”.
You may not have done a thorough analysis, but surely you must agree that reducing the cost of government this way is an important step toward reducing the cost to build homes.
