Definition
NI 21-101 (Marketplace Operation) distinguishes between recognized exchanges (TMX Group's TSX and TSX Venture Exchange, Cboe Canada, and NEO Exchange) and ATSs. An ATS must register with the applicable securities regulator(s) in each province where it operates, but it does not need to go through the full exchange recognition process. ATSs cannot list securities and must comply with fair-access requirements (they cannot arbitrarily deny access to qualified participants). UMIR applies to all CIRO dealer members trading on both recognized exchanges and ATSs. Key Canadian ATSs include Liquidnet (institutional block crossing), MatchNow (dark pool operated by Cboe Canada), and Alpha (operated by TMX Group). Because ATSs are required to report all trades to the marketplace that the security is listed on, trade reporting is consolidated. The best-execution obligation under UMIR 5.1 requires dealers to consider all lit and dark marketplaces, not just the listing exchange.
