With the rising cost of food…

With the rising cost of food and rising costs in shipping and importing food, it seems completely illogical and irresponsible to build on land that should be protected.
Building more homes instead of supporting farmland and local agriculture is not in the best interest of Canadians. Why is there not an effort to utilize non-protected land and areas where there are old rundown habitations to build residential homes?? This is not protecting the Ontario that is beautiful and respectful of its lands.
