Thoroughness, availability and solid expertise in indirect taxes. Three factors that send Nicolas’s clients a clear message: They’re in good hands.

Nicolas Désy is a partner in the firm’s Tax Group in Montreal. His practice focuses primarily on indirect taxes.

Before joining McCarthy Tétrault, Nicolas practised with a major professional services firm, where he acted for clients in disputes involving sales taxes, customs and international trade. Prior to that, he practised with a tax group at a national law firm.

Meticulous, human and pragmatic, Nicolas builds relationships of trust with clients, providing them with advice about supply chain planning and corporate structures, with regard to indirect taxes, imports, exports and international trade. He also advises and represents clients in dealings with tax authorities, in contexts such as disputes and challenges.

Our clients can also count on Nicolas’s skill in explaining technical concepts, including indirect taxes, and in passing on his knowledge through training on import compliance issues. In addition, he has prepared customs compliance manuals for his clients, including multinational corporations involved in cross-border activities.

Nicolas obtained a Bachelor of Business Administration (BBA) with joint majors in Economics and International Management (Mercure Award) from HEC Montréal in 2005, a Bachelor of Laws (LLB) from Université de Montréal in 2008, and a Master of Laws, Taxation Option (LLM) from Université de Montréal and HEC Montréal in 2011. He was called to the Québec Bar in 2009.

Nicolas is a member of the Young Bar of Montréal, the Association de planification fiscale et financière and the Canadian Tax Foundation. He is also a co-founder and member of the board of Testicular Cancer Canada and founder of Pro Bono Students Canada at Université de Montréal.
