Yes, FINTRAC regulates cryptocurrency businesses for anti-money laundering and counter-terrorist financing purposes. Under the Proceeds of Crime (Money Laundering) and Terrorist Financing Act (PCMLTFA), cryptocurrency dealers are considered money services businesses (MSBs) and must comply with FINTRAC regulations around implementing a compliance program, record keeping, reporting large transactions, etc.
However, depending on the nature of the business, the purview of CSA, CRA, etc. may also apply.
