The latest housing report by RBC Economics Research says the cost of owning a home increased the most in Ontario and British Columbia.

The higher monthly costs for owning a home were driven by increased mortgage rates and further appreciation in home prices, the report says.

The report says home ownership costs in B.C. have neared the all-time highs reached in 2008.

The RBC report also says it expects a temporary easing in housing-ownership costs because of the recent drop in mortgage rates and signs that home prices are stabilizing in many markets.
