Portrait of Chantale Cousineau-Mahoney

“I strive to build trusting long-term relationships with all my clients, from individuals and start-ups to more seasoned corporations and not-for-profit organizations”

With a commitment to provide value-added and cost-efficient legal solutions in a wide spectrum of business and estate law, Chantale focuses her practice in corporate transactions (including setting up new business structure or the restructuring of an existing one, business purchase and sale and governance matters), the negotiation and drafting of commercial agreements (such as goods and services contracts, licensing agreements, joint venture, partnership and shareholders agreements and commercial leases), and wills and estate planning (including business succession planning and reorganization). Fully bilingual, Chantale is always pleased to offer legal advice in English and French.

Chantale graduated from the University of Ottawa French Common Law program and was called to the Ontario Bar in 2017. While in law school, she won the Tax Executives Institute Award for highest marks in tax law and volunteered at the University of Ottawa Employment Law Clinic. Chantale also holds a Master’s in Business Administration (MBA), and she has her Chartered Professional Accountant designation (CPA, CGA). Chantale’s background in business and accounting is a unique and beneficial addition to her legal skill set. It allows her to work collaboratively with accountants and financial planners alike to meet her client’s legal and financial objectives.

Before her law practice, Chantale had an extensive career in the federal public service where she held the positions of Assistant Deputy Minister, Vice President and Chief Financial Officer in government departments and Crown corporations. She spearheaded several reorganizations and negotiated multi-million-dollar funding proposals and contract agreements in the health, security, and communications sectors. This experience has allowed her to counsel several of her clients on legal issues and considerations with respect to government procurement.

Chantale is a member of the Law Society of Ontario and belongs to the Canadian Bar Association. She provides pro bono services, as needed, to the Council on Aging of Ottawa.

Interesting Fact:
Chantale grew up on a dairy farm where she gained her deep appreciation for nature and love of animals. Since in law school, she has been a strong advocate of seniors’ rights and inclusion.
