In BC, an expert panel commissioned by the provincial government has estimated that $5.3 billion/year is laundered through real estate transactions (pg. 54): https://news.gov.bc.ca/files/Combatting_Money_Laundering_Report.pdf. Even if every single cryptocurrency trade in Canada was done by criminals for the purpose of money laundering, it wouldn't come close to the scale of money laundering in BC, in one year, using real estate.
For years now I've been on panels where people bring up money laundering using cryptocurrency (always without evidence). To the extent that anyone took this idea seriously, they've apparently been looking in the wrong place. I hope that this new research about money laundering helps refocus Canadian regulators' attention on the boring, old-fashioned reality of financial crimes in Canada, and around the world.
