The Canadian Securities Administrators, or CSA, and Investment Industry Regulatory Organization of Canada, or IIROC, have issued guidelines for crypto trading platforms operating in the country to avoid “advertising and marketing materials that could mislead investors.”

In a Thursday publication, the Canadian regulators’ guidelines warn crypto companies not to advertise “gambling style” promotions in which an investor is encouraged to sign up within a given time limit to take advantage of a reward or opportunity. Although there was no clear guidance on social media postings, regulators advised that crypto trading platforms set up an internal review team to oversee and approve all communication and to establish a process to verify compliance with the regulations.
