The group that represents mortgage brokers across Canada was in Ottawa on Tuesday to urge parliamentarians to tinker with their recent rule changes, and hit the brakes on any new ones.

Mortgage Professionals Canada, who represents more than 11,000 mortgage brokers, urged lawmakers to rethink rule changes introduced last October aimed at reining in consumers who may be taking on too much debt to buy a home. Among the major changes was the implementation of a "stress test" whereby borrowers would be judged on their ability to pay their mortgage assuming that rates were much higher than they are right now.

The yardstick for that test is what's known as the Bank of Canada's qualifying rate — the average of the posted rates at Canada's Big 5 banks — which is currently 4.64 per cent.

While it's easy to get a mortgage rate below three per cent at the moment, the new "stress test" means that borrowers have their finances gauged against a much higher bar, in case real rates inch up. The aim was to clamp down on speculation and high debt, but the result has been to reduce purchasing power for new borrowers, MPC says.

A homeowner making $80,000 a year would likely qualify for a 2.5 per cent mortgage and allow them to buy a $400,000 home, CEO Paul Taylor said. But with the higher stress test level, they'd only qualify for a home worth about $320,000 — a reduction of about 20 per cent, he said. 

Other changes to limit portfolio reinsurance have disproportionately hurt smaller lenders, which helps the big banks. And setting the stress test level based on posted rates at big banks allows them to set their own competitive advantage, Taylor said at a parliamentary committee last month.

"These are costs that will be passed on to consumers," he said.

Instead of setting the stress test based on a level the big banks can skew to their advantage, "set the stress test based on a market rate," MPC said, or have the Bank of Canada set a rate that is independent of the average of the banks posted rates.

Worse still, Taylor said Tuesday, is that the new rules have done nothing to cool the housing markets in hot places like Toronto and Vancouver, while harming the market elsewhere. "By virtue of making it harder to get on the property ladder, there's an oversupply in some markets," Taylor said.

Meanwhile, "Toronto and Vancouver have supply issues," he said, "so they're almost isolated because people will pay whatever is required to get into the market."

Other markets are being hurt by tougher rules, and that's playing out in sales and prices. While the winter months are typically a time of seasonal slowdown for home sales, MPC says new mortgage originations are down by about 20 per cent since the new rules kicked in.

"So let's slow down and hit pause," MPC chair Mark Kerzner said.

He said the group isn't necessarily asking Ottawa to overturn the new rules, but at least consider tinkering with them and certainly avoid bringing in any new ones.

"Take 12 to 18 months to assess the impact of changes already made," Kerzner said.

Budget time

The push comes as Ottawa is set to unveil an annual budget that may well contain new measures to rein in house prices. While the most recent figures suggest prices are indeed flattening nationally, they were still up by 15 per cent in Vancouver and by 22 per cent in Toronto in the year up to January.

While Ottawa considers what to include in the budget, the mortgage group is urging them to not take any drastic and unnecessary action because of isolated pockets of danger.

The new rules "disproportionately affect competitive positions of small and mid-sized lenders," Kerzner said. "There's a real and growing sentiment that activity in Toronto and Vancouver is negatively impacting those in the rest of the country."
