In 1960, Lavy Becker placed an ad in the Montreal Star, inviting people to a meeting to form a Reconstructionist group, which became incorporated in 1960 and 1962. The founding members worshipped in a variety of locations. By 1964 they purchased land and in 1966 the habitant-style building was completed, the first synagogue in Hampstead (and the only Reconstructionist one in Canada, until recently). The institution was principally referred to as the Reconstructionist Synagogue, so that its objectives and form of Judaism practiced would be apparent. The Hebrew name "Dorshei Emet" was adopted in the late 1970s. An addition was built in 1977 due to membership growth, and secondary High Holiday services were required from the late 1980s on. Lavy Becker was the rabbi from 1960-1977 and helped the synagogue acquire Torahs from Egypt, Casablanca, and Trinidad. Dorshei Emet has its own cemetery and is one of the oldest and largest Reconstructionist congregations in North America.
