In 1857, Birks was hired as a clerk at Savage and Lyman in Montreal, reputed to be the finest jeweller and watchmaker in the Province of Canada at that time. Although Birks eventually became a partner in the firm in 1868, the company's later financial difficulties encouraged Birks to leave in 1877 With an investment of C$3000, Birks opened his own small jewellery shop in 1879 on Saint Jacques Street in the heart of Montreal's financial and commercial district. In 1893, Birks went into partnership with his three sons (William, John and Gerald), and the name of the firm became Henry Birks and Sons.
