01 — The ranking
The Canada Mergers & Acquisitions board
Sartori's view of the best Mergers & Acquisitions law firms in Canada groups 7 firms by relative Mergers & Acquisitions market position in Canada. Tiers are plain-language labels only — never scores — and within-tier sequence rotates without implying rank.
This band holds the firms whose Mergers & Acquisitions presence defines the Canada standard. Labels are editorial words, not scores; monthly order inside the tier carries no meaning.
Highly active firms show sustained Mergers & Acquisitions mandate flow and visible deal-side bench strength in Canada, just below the market-leader band. Order inside the tier is non-hierarchical.
Notable entries flag real but lighter Mergers & Acquisitions footprints in Canada. They are not a lower rank of the bands above; they document firm presence the board would otherwise omit.
All counts are shown as bands, never precise headcounts. Notable firms sit outside the tiers by design: verified minimal presence, not assessed at full tier depth.

Tier placement is derived from this public mapped data; a per-firm public-source ledger is compiled for firms in the annual research pass and applies to those firms' factual claims, not to tier membership. No third-party legal-directory bands are used as an input.
