Environmental experts say the Ford government's proposal to build thousands of homes in parts of the Greenbelt while adding other protected land elsewhere will cause a host of ecological problems. Last Friday, the provincial government announced a proposal to build 50,000 new homes in some areas that are now part of the Greenbelt, and add 9,400 acres of protected land elsewhere. Premier Doug Ford says it's all part of the province's plan to tackle the housing crisis by building 1.5 million homes over the next decade — as the federal government pledges to start bringing in half a million immigrants a year.
