The answer is yes. In any community, regardless whether it already has a minimum percentage of affordable homes, the minimum will be 20%.
If in some communities, like Windsor, the city or partners want to elevate that to a higher proportion, that will be even better, but it cannot be below 20%. As you've pointed out, these community homes are built in mixed settings with mixed partnerships and uses.
Again, I would invite everyone either living or working in the national capital region to visit Wateridge Village in Ottawa. It's a remarkable example of what the leadership of Canada Lands Company can do in little time with great impact.
