Mergers and Acquisitions

Modern skyscrapers in business district.

Mergers and acquisitions transactions, whether large or small, have inherent complexities that need to be clearly understood and properly addressed. Experienced legal counsel is essential on all M&A transactions and for all clients, ranging from local start-ups to global conglomerates. Osler's M&A group is consistently ranked Band 1 in Chambers Canada, one of the world's leading legal publications. With decades of experience advising successfully on M&A transactions, Osler can be trusted to provide clients with the right level of legal advice required to lead a successful deal, for several reasons:

  • Involvement in High Volume and Range of Transactions – We are effective at advising on and staffing all types and sizes of transactions, be it for domestic, cross-border or multi-national companies. We have designed and implemented innovative legal structures that have revolutionized the M&A landscape and continue to provide valuable solutions to our clients.
  • Breadth and Depth of Related Expertise – Our leading M&A practitioners are complemented by top-ranked expertise in tax, competition/antitrust, securities/regulatory, banking & financial services, litigation, pensions, employment/executive compensation and all other specialized areas that are key to effecting 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 – We 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.
