In Canada, Ortho Products began operations in Montreal in 1941. The company started with one product and three employees and it was one of the first companies in Canada to make oral contraceptives. Moving to Toronto in 1944, the company outgrew a number of rented facilities until its own facilities were constructed in 1955. Continued growth required a number of plant expansions. Ortho Pharmaceutical Canada merged with McNeil Pharmaceutical Canada in 1991, and merged with Janssen Pharmaceutica Canada in 1995 to form Janssen-Ortho.
