Deloitte Legal Canada LLP (Deloitte Legal Canada) is a national law firm founded over 16 years ago. As an affiliate of Deloitte, Deloitte Legal Canada has access to Deloitte’s global network of subject specialists and advisers, in supporting clients and has the privilege of providing legal counsel to many of the world’s largest companies. Deloitte Legal is one of only a few truly global legal service providers, with over 2,000 legal professionals worldwide in 70 countries.

Our lawyers have access to Deloitte’s extensive worldwide network of subject specialists, advisers, and clients, which enables us to offer legal counsel to many renowned multinational companies. Many of our senior practitioners joined Deloitte Legal Canada from the ranks of the major Canadian law firms with the vision of leveraging Deloitte's deep relationship and knowledge of its clients and their business needs to provide them with world-class legal advice firmly rooted in the realities of their businesses. Deloitte Legal Canada addresses challenges with comprehensive thinking powered by experience and insights drawn from diverse business disciplines, industries, and global perspectives. We bring together legal advice, strategy, and technology to develop innovative solutions and create value for our clients and their businesses.

Deloitte Legal* is one of only a few legal service providers operating with a global network, with a presence in more than 70 countries, and with practitioners working closely across borders. Our global legal network provides a strategic perspective, helping clients to meet their local responsibilities and thrive in the global marketplace. Our global presence provides a one-stop-shop for clients.

*“Deloitte Legal”, in Canada, means Deloitte Legal Canada LLP and, elsewhere, means the legal practices of Deloitte Touche Tohmatsu Limited member firms or their affiliates that provide legal services. For legal and regulatory reasons, not all member firms provide legal services.

Our team is regarded for its wealth of knowledge and experience in all areas of Canadian tax law. Deloitte Legal Canada generates mandates from corporations and major non-profit organizations. Our team advises clients at all stages of the dispute resolution process, including international income tax disputes, customs disputes, and various provincial tax matters, where we provide representation at all court levels. Our firm also offers support on cross-border tax issues. In parallel to our ever-growing Tax practice, Deloitte Legal Canada has launched an Employment and Labor Law practice and a Data Privacy and Cybersecurity law practice, both in 2019.

Deloitte Legal Canada employs technology to pioneer innovative legal solutions. As part of the Deloitte organization, which has collected several technology-related accolades and has a strong track record in providing technology solutions, both through in-house capabilities and alliances with technology companies, we combine legal skills with innovative service delivery, solution platforms, and intelligent data analysis to find the right solutions for our clients.

Deloitte Legal Canada has access to industry specialists and a wide range of professional services spanning strategy, finance, human capital, risk, technology, audit, tax, and, of course, legal, to help tackle the most complex business problems. Our internal cross-business collaboration facilitates developing end-to-end solutions for clients.
