Many believed that Canadian leverage was too high compared to US and UK firms, but the Canadian economy is stable, our lawyers are talented and the merger announcements keep coming. Until recently, the Canadian market has been relatively sheltered from major international mergers. Until Norton Rose merged with Ogilvy Renault as of June 1, 2011, and with long standing Alberta based MacLeod Dixon as of January 1, 2012. 
Just last week, on November 7th 2012,  SNR Denton, Salans and Canadian firm Fraser Milner Casgrain announced a three way merger, to create a new global law firm with about 2,500 lawyers and 79 offices. And today, another announcement, effective June 1, 2013 involves Norton Rose again, but this time with Fulbright and Jaworski.  The combined firm will be a global legal practice that will include 3,800 lawyers in 55 offices across the United States, Europe, Asia, Australia, Canada, Africa, the Middle East and Latin America.  Can you imagine the conflicts that had to be cleared for that one? 
These recent mergers are game changers for US, UK, Canadian and all International firms.  To deny its impact and influence, whether the future brings success or failure would be inane.  It will have an impact and all I can hear is  R.E.M. playing in my head…. “it’s the end…..”
