Here's the October 2018 report from CMHC on rental vacancies. Burnaby had a significant spike in vacancies in purpose-built and private apartments. Prices should be soft from the oversupply around Metrotown. But, vacancies are still tight in CoV and Surrey. Have to wait for another recession before a big fall in condo prices.

I'll expect more of the same from the 2019 report.
