How are the top firms in Montreal ranked?
Firms are ordered by the Sartori Firm Index — a 0–100 score from public signals (scale, reach, live hiring). This page lists firms with a recorded attorney presence in Montreal, ranked by their overall Index. It reflects public footprint and momentum, not the quality of any firm's Montreal office.
Does a presence in Montreal mean a large local office?
Not necessarily. The Index records that a firm maps attorneys to the Montreal market on public sources; it does not claim a specific office size. Headcount is shown only as ranges.
