The British Columbia government will unveil its long-awaited housing strategy on Tuesday, taking aim at skyrocketing real estate prices and soaring rents that have crippled affordability in the West Coast Canadian province, particularly in Vancouver. The left-leaning New Democratic Party (NDP) came to power last year with a pledge to improve housing affordability and its first full budget is expected to include measures to curb speculative demand, crack down on tax cheats and money laundering, and stabilize housing markets. Foreign buyers have been largely blamed for Vancouver's red hot property market, where the gap between home values and incomes has widened rapidly in the last five years, hitting levels well above any other major Canadian city, according to data analyzed for Reuters.
