Finance Minister Bill Morneau is urging Canadians to just wait and see after his changes to mortgage rules failed to cool down home prices in certain cities across the country. In December, Morneau announced that mortgage holders would need to make minimum down payments of 10 per cent on any portion of a home's price above $500,000, up to $1 million. The presumable aim was to cool down staggering home prices in some of Canada's hottest markets — but that hasn't happened yet, and the rule has been in effect since Feb. 15. In fact, things seem to have gone the other direction in certain cities.

Regardless, Morneau is optimistic that the new rule will have some impact down the road. "We're only one month into that change, we hope that change, and we expect that change will have some impact," the finance minister told Business News Network (BNN) on Friday. “We want to make sure that our housing market stays one that is working effectively. And as we see challenges, we will of course think about ways that we can respond that ensure that our market remains stable.”

Last month, National Bank economist Marc Pinsonneault said anyone who secured a mortgage prior to Feb. 15 could take until July 1 to purchase a home. But experts question whether the change will have its desired impact at all. UBC professor Tsur Somerville told The Huffington Post Canada that it's "going to have less of an effect than in places where the economy is weaker." For example, in a city like Calgary, where housing sales fell 11 per cent in March compared to a year ago, Somerville said the new rules won't do much for prices. "If there is going to be any effect, it's going to be dampening the demand in those places," Somerville said. "Where housing markets are weak and people are concerned about their resources, asking them to put more money down [on a mortgage] is going to be more problematic." His comments echoed analysis by CIBC, which found that only 3.9 per cent of new Canadian mortgages would be affected. Calgary, it said, would be hit hardest.

And even if the new rules do make a difference, they're "small potatoes" compared to changes the Conservatives brought in, Somerville added. In 2012, then-finance minister Jim Flaherty cut the maximum amortization period for mortgages on government-insured homes from 30 years to 25 years.
