Nathalie Gagnon listens closely to her clients’ needs, allowing her to identify a transaction’s main challenges. She brings an extraordinary amount of energy to every one of her files.

Nathalie Gagnon is one of the co-leaders of the Mergers & Acquisitions team. Over the last 15 years, Nathalie has represented many businesses and their executives in connection with the negotiation and conclusion of purchases and sales of private corporations. Her proactive approach allows each of Nathalie’s clients to feel that they are her top priority, regardless of the nature of the transaction, the size of the business or its sector of activities.

She also assisted businesses and financial institutions in connection with corporate financing and strategic investments, developing particular expertise in leveraged buyouts.

Nathalie has a special interest in transactions set-up to ensure the successful transition of ownership of a business, whether through employee incentives or management buyouts. Working closely with her clients, she measures the financial, strategic and emotional impacts of their decisions.

Over the years, Nathalie has taken a deeper interest in business practices and, accordingly, in shareholders’ agreements, which can prevent many disputes. She therefore works with entrepreneurs and investors in negotiating and drafting such agreements.

In 2014, Nathalie received one of Canada’s most coveted and prestigious legal awards, Lexpert Rising Stars: Leading Lawyers Under 40. This award is considered by many in the legal community to be one of the most important in the country.
