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.
