The national house price index fell 4% year-over-year in May, matching April's decline. Regional differences persist, with gains in Quebec and the Prairies, stability in Calgary and Edmonton, and softness in B.C.'s Lower Mainland and southern Ontario. Ontario's new home sales rose due to an HST rebate, possibly delaying existing home purchases. Condo prices continue to decline by 5-7%, with no major shifts expected soon.
