About Bertrand Deslauriers Avocats (BDIA)

BDIA, short for Bertrand Deslauriers, Avocats, is a small Montreal law firm that has practised immigration and citizenship law since 1984. The firm's name comes from its founding partners, and it also handles business and technology law work. Its immigration practice covers the range of federal and Quebec files, from an initial consultation on a client's options to contesting an unfavourable decision, responding to a government request, applying for a visa or permit, or opening a citizenship or asylum case.

The firm is based in Old Montreal, on rue Saint-Paul Ouest, and also keeps a Toronto phone line for clients in Ontario. Its own site notes that its lawyers are regularly asked to speak at conferences and training sessions on immigration law, work that sits alongside the day to day filing of visa, permit, and citizenship applications.

The neighbourhood

BDIA's Montreal office sits on rue Saint-Paul Ouest, in the heart of Old Montreal. The street was laid out in 1672, which makes it the oldest in the city, and for many years it served as Montreal's main thoroughfare. It's still lined with cobblestones, and runs past landmarks such as Bonsecours Market and the Notre-Dame-de-Bon-Secours Chapel, a short walk from the address where BDIA has practised immigration and citizenship law since 1984.
