UPDATE: 2/11/14, 8:25 a.m. EST. The Am Law Daily reported late Monday that Dentons is in play for between 30 and 40 Heenan Blaikie partners.

Only a few days after DLA Piper announced that it was in talks to open offices in Calgary and Toronto by picking up between 55 and 70 lawyers from dissolving Canadian firm Heenan Blaikie, the world’s largest firm by gross revenue and attorney head count confirmed that negotiations have ended without a deal.
