Pfizer Inc.’s $68 billion purchase of Wyeth closed on October 15, 2009, after regulators in the United States and Canada cleared the deal, making Pfizer the world’s largest drug manufacturer by revenue. Cassels Brock lawyers Mark Nicholson, Chris Hersh, Yana Ermak and Nicole Washington, assisted by a large team of other Cassels Brock lawyers and students, acted as counsel to Pfizer on the competition aspects of this landmark transaction which, in addition to its remarkable size, was the first cross-border merger completed under the new Canadian competition two-tier regime.
