The Peace Tower is pictured on Parliament Hill on Monday, September 15, 2014. The parliamentary budget officer is questioning whether the Liberals' decade-long housing strategy will alleviate a housing crunch as the government promises. The Liberals unveiled the 10-year national housing strategy in late 2017, which at that time carried with it a price tag of more than $40-billion in federal, provincial and territorial spending.
