Our experienced team advises on a wide range of M&A transactions with a ‘client first’ approach.

Osler’s M&A group, consistently ranked Band 1 in Chambers Canada, advises on all types and sizes of transactions and has deep experience from decades of deal flow, be it for domestic, cross-border or multinational companies. Our lawyers have designed and implemented innovative legal structures that have revolutionized the M&A landscape and continue to provide valuable solutions for our clients.

Our firm can be trusted to provide clients with the right level of legal advice required to lead a successful deal, for several reasons:

  • Band 1 ranking in Chambers Canada, one of the world’s leading legal industry ranking publications – As well, for a number of years Osler has been the highest ranked Canadian law firm in M&A league tables published by Bloomberg and LSEG (formerly Refinitiv). Our firm advises on domestic, cross-border, and multi-jurisdictional transactions involving public companies, private companies, private equity sponsors, emerging companies and start-ups, global conglomerates, pension funds, sovereign funds, and financial advisors.
  • Breadth and depth of related expertise – Our leading M&A practitioners are complemented by top-ranked expertise in tax, competition/antitrust, securities/regulatory, banking and financial services, litigation, pensions, employment/executive compensation and all other specialized areas that are critical to a successful M&A transaction. Taxation, for instance, is integral to accomplishing strategic M&A initiatives and no other Canadian law firm has been so consistently recognized for the excellence of its tax practice.
  • Client focus – Osler lawyers understand the business imperative behind a transaction and the business environments in which our clients operate. Our “client first” approach pervades every aspect of our firm culture and we bring that approach to the way we structure a deal, negotiate a deal, mitigate risk, and staff and efficiently manage files.
