Antonin Favreau is the founder of Favreau Law Firm and a Canada and United States immigration lawyer based in Montreal. He focuses on immigration and visa applications for entrepreneurs, investors, workers, students, managers and families seeking to relocate, build businesses or pursue opportunities internationally.

What Antonin Favreau Does

Antonin advises clients on a broad range of Canadian and United States immigration matters, including:

• Canadian Start-Up Visa applications
• Quebec investor immigration matters
• Business immigration and entrepreneur applications
• EB-5 investor petitions
• L-1 visa applications
• Permanent residence applications
• Family sponsorship applications
• Naturalisation and citizenship matters
• Business plans for immigration applications
• International mobility advice for companies and individuals

He has particular experience assisting entrepreneurs and investors who wish to establish or acquire businesses in Canada or the United States, as well as advising companies on the international movement of key personnel.

Why He Stands Out

Antonin combines detailed immigration law knowledge with significant international experience. His work has taken him from Montreal to Beijing, Shanghai and Ecuador, allowing him to understand the cultural, commercial and practical considerations that frequently arise in global migration matters.

He has represented more than 1,000 applicants from countries including China, Taiwan, Korea and Iran. His experience includes preparing applications, developing immigration business plans, coaching clients for interviews and organising exploratory business visits to Canada and the United States.

This international background allows him to provide practical advice that goes beyond completing forms. He helps clients understand the wider business, timing and strategic issues that may affect the success of their immigration plans.

Business and Investor Immigration Expertise

Antonin has developed particular expertise in business and investor immigration. He assists with Canadian Start-Up Visa applications, including submitting cases to business incubators and helping applicants obtain letters of support.

His work has also included Quebec and federal investor immigration matters, provincial nominee programmes, EB-5 petitions and L-1 applications. He prepares immigration business plans, advises on company purchase agreements and helps clients structure applications around credible commercial objectives.

For entrepreneurs and investors, this combination of immigration and business knowledge can be particularly valuable when an application depends on demonstrating both eligibility and the commercial viability of a proposed venture.

International Experience

Antonin began his legal career with the Government of Quebec, where his work included preparing legal advice, negotiating settlements and appearing before the Administrative Tribunal of Quebec and the Superior Court.

He later moved to China and spent several years practising immigration law in Shanghai and Beijing. During this period, he advised clients on Canadian investor, provincial nominee and skilled worker immigration programmes while delivering seminars and supporting applicants throughout the immigration process.

He founded his own practice in 2014 and has continued to advise clients across Canada, the United States and international markets.

Professional Recognition

Antonin has been recognised as a recipient of a Top 25 Global Migration Award for four consecutive years. This recognition reflects his continued work in international and business immigration and the confidence placed in him by clients and professional peers.

He has also participated as a speaker and panellist at international immigration events, sharing his experience of business migration programmes and global mobility.

Qualifications and Admissions

Antonin earned his Bachelor of Laws from the Université du Québec à Montréal. He has been a member of the Barreau du Québec since 2006 and has also held membership of the Illinois Bar since 2014.

He completed the Federation of Law Societies of Canada’s National Committee on Accreditation process and holds experience advising on immigration matters involving both Canada and the United States.

Commitment to Clients

Antonin believes international mobility should be approached with creativity, careful preparation and a clear understanding of each client’s goals. Whether advising an investor, entrepreneur, student, worker or family, he focuses on developing a strategy that reflects the client’s circumstances and intended destination.

His international outlook, practical approach and experience handling complex business immigration files help clients move forward with greater clarity and confidence.
