Felt the absence of an Armenian Church under the umbrella of the Holy See of the Catholicosate of Cilicia in their community. Near the end of 1982, an official petition was delivered to the prelacy of Canada and Eastern United States, that on February 28, 1983 resulted in an approval in constructing a formation of a new church community.

They erected what is now known as St. Mary Armenian Apostolic Church at 45 Hallcrown Place to the beside the already built Armenian Community Centre. The church was consecrated by His Holiness Karekin II, Catholicos of the Great House of Cilicia of blessed memory in 1990.
