it's not a difficult equation.
if you're going to let in x refugee families, you need to build x low rent rental units for them. at least.
if you don't do that, you're going to get social unrest, as low income canadians fight with refugees over dwindling access to cheap housing.
i understand that your typical upper class liberal has no idea, but the actual politicians need to figure this out and get to fixing it - or deal with the consequences.
