An informative article in the Vancouver Sun (hello, Justin Trudeau, you might want to think again about your massive plan for ongoing multiple entry visas):

"The phenomenal popularity of Canada’s new 10-year visas is a key factor behind the latest housing booms in Vancouver and Toronto, say immigration specialists."

“I often travel to China, where I see pride many take in investing their money in Canada” —­ particularly by taking advantage of 10-year visas to buy real estate, said George Lee, an immigration lawyer."

"In 2015, Ottawa issued 390,000 10-year, multiple-entry visas to residents of Mainland China, the largest cohort"

"The multiple-entry visas have caused a migration “chain reaction,” Lee said, which often leads to international students becoming proxies for offshore real-estate investors."

"...government continues to refuse to provide the information that would allow a researcher to ascertain whether house buyers are (one of 72,000  Chinese) foreign students in Canada"
