Wow! In 1 Day, 2 different entities tighten mortgage rules

First the finance minister came up to the plate to tighten mortgage rules earlier today.  And then later today the OSFI did not want to outdone.
 From the Financial Post OSFI lays mortgage rules finalized mortgage rules; mortgage brokers not so happy

Canada’s banking regulator announced finalized guidelines for mortgage lending that along with other measures unveiled today by Finance Minister Jim Flaherty are aimed at cooling the country’s frothy housing market.
The Office of the Superintendent of Financial Institutions first proposed the guidelines back on March 19, as part of an international initiative spearheaded by the Financial Stability Board in Basel, Switzerland.
The new guidelines, which come after much discussion with industry, are designed to compel lenders to look more closely at the credit history of borrowers even when mortgages are backed by the federal government and to limit the level of risk exposure.

Among the major changes:
— The maximum loan to value on home equity lines of credit (HELOCs) is cut to 65% from 80%
— The loan to value should be re-calculated upon any refinancing and whenever the lender deems prudent
—HELOCs will continue to as revolving lines of credit with no specific amortization period. However, OSFI says lenders must now expect borrowers to have the ability to fully repay HELOCs over time.

All this on the heels of Mark Carney saying from the Financial Post "Canada’s relatively healthy economy has been largely based on borrowed money, but the situation cannot go on indefinitely", Bank of Canada governor Mark Carney warned Thursday.
