Best Merger & Acquisition Lawyers in Ontario

1. About Merger & Acquisition Law in Ontario, United States

Note on jurisdiction: Ontario is a province in Canada. If you meant Ontario, California or another Ontario location in the United States, the legal framework will be different. This guide focuses on Ontario, Canada, where M&A law involves federal competition rules and provincial securities regulation. It is written for Ontario residents seeking practical guidance from a solicitor or lawyer (the Canadian term for a lawyer who may practice in M&A matters).

In Canada, M&A law typically covers pre-close regulatory clearance, fiduciary duties of boards, due diligence, disclosure obligations, representations and warranties, and closing conditions. The federal Competition Act, administered by the Competition Bureau, governs notifiable mergers and anti-competitive conduct. Provincial securities regulation, including the Ontario Securities Act and policies from the Ontario Securities Commission, governs takeovers and issuer bids for public companies in Ontario. For foreign investment, the Investment Canada Act reviews significant investments to safeguard national interests.

Cross-border deals require aligning Canadian and foreign law, including potential review under the Investment Canada Act and cross-border disclosure obligations. In Ontario, deal documents often include regulatory clearance conditions, break fees, standstill agreements, and robust integration plans.
