About Alphonse Latham LLP

Alphonse Latham LLP is a Toronto law firm that combines a US and Canadian immigration practice with Canadian employment and human rights law, workplace investigations, and entertainment and intellectual property work. It's a small team working out of First Canadian Place in the city's Financial District, and it serves clients in English, French, and Haitian Creole.

Founder Carl Alphonse is a member of both the New York Bar and the Ontario Bar and is licensed as a Foreign Legal Consultant in Ontario. Close to a decade into practice, Carl Alphonse has handled more than 1,000 immigration applications covering business, family, and humanitarian cases on both sides of the border. Partner Lavinia Latham, the firm's namesake, focuses on employment and human rights law and has appeared before courts and tribunals across Ontario and Canada, including the Supreme Court of Canada.

The firm's workplace investigations team takes a trauma-informed approach to harassment and discrimination complaints, and its entertainment and intellectual property practice works with creators, production companies, and growing brands on deals and IP protection. Corporate training on workplace respect and inclusion rounds out the practice.

The neighbourhood

Alphonse Latham LLP's office is in First Canadian Place, at the corner of King and Bay in Toronto's Financial District. The tower opened in 1975 and was Canada's tallest building for about 50 years, until a new residential tower surpassed it in 2025, and it still serves as the global operational executive office of the Bank of Montreal.

That puts the firm in the middle of Toronto's business core, a fitting base for a practice that spends much of its immigration work on entrepreneurs, professionals, and companies moving people across the Canada-US border, alongside its employment and human rights files.
