The Wellesley Institute’s Michael Shapcott warns in the lead letter in today’s Toronto Star that bad gentrification in Toronto has led to increased inequality, poor health, a loss of affordable and supportive housing and deeper divisions between rich and poor. He cites research reports from the Wellesley Institute and others on the costs of growing inequality. Mandatory inclusionary housing plans have been adopted by hundreds of US cities and offer a positive alternative. Toronto urgently needs a city-wide plan to ensure healthy inclusive neighbourhoods for all.
