Just have a look at what is happening in Oakville and Mississauga.  Talk to any school and you'll see the same story.  Sudden influx of Chinese kids living in expensive house with no father who is still back in China working.   The mother declares $35K in income and so pays no income tax.

Home grown Canadians pay for their OHIP coverage, use of roads, and other infrastructure. 

I don't begrudge the families moving in because the problem lies with our inadequate laws regarding foreign investment.  Canadians have to start making this an issue at the next provincial and federal election.  In Ontario that is June 2018.  Your Millennial kids and the next gen will never own a home in the GTA, GVA, and eventually GCA and GOA.
