The federal government introduced legislation that would enshrine its housing agency as a Crown corporation on Thursday, giving it land acquisition authority as well as the ability to partner with private developers — as questions remain over the number of units it intends to build. “We are making a generational decision that affordable housing is, and must remain, a top priority of the federal government, and that we play a key role, alongside local, provincial and territorial governments, in ensuring that everyone in Canada has a safe and affordable place to call home,” said Housing Minister Gregor Robertson. Robertson said the existing Canada Lands Company, a Crown corporation that redevelops federal properties, would be folded into Build Canada Homes. …Unclear in the legislation is how many units Build Canada Homes intends to actually build, or other performance indicators.
