Claim: Congregation Dorshei Emet adopted the name in the late 1970s when it had under 180 member families.
Evidence: The congregation adopted the name Congregation Dorshei Emet in the late 1970s, though it was still also known as "the Reconstructionist Synagogue of Montreal". Ron Aigen was hired as the congregation's first paid rabbi in 1976. That year the congregation, which had under 180 member families, added an extension to its building.
