Alternative Trading System (ATS)

A non-exchange marketplace that matches orders in listed securities.

Definition

Canadian ATSs (e.g., NEO, CSE2, Liquidnet, MatchNow) compete with the TSX/TSX Venture for order flow. UMIR Rule 5.2 (Best Execution) requires dealers to consider all marketplaces, not just the listing exchange. ATSs typically charge lower fees and may offer dark or hidden order types.
