The 19th Edition of The Best Lawyers in Canada™ and its accompanying “Lawyer of the Year” recognitions have been publicly released and are available now on www.bestlawyers.com. Since it was first published in 1983, Best Lawyers® has become universally regarded as the definitive guide to legal excellence. Best Lawyers lists are compiled based on an exhaustive peer-review evaluation, this year Best Lawyers recognized 8,362 lawyers in 77 practice areas, across 26 metropolitan areas. Lawyers are not required or allowed to pay a fee to be listed; therefore, inclusion in Best Lawyers® is considered a singular honour.
