The blessing of the cornerstone for the future, St. Basil the Great Ukrainian Catholic Church, was conducted by Bishop Isidore Boretsky of Toronto, on September 1, 1957. The new church to be built on the corner of 9th and Provost Streets, Lachine, Quebec, was to serve 250 persons or about 70 families in the Lachine/Montreal area. The parish president at that time was Vasyl Kravetz

A contract signed in 1955 between the Building Committee for St. Basil’s parish and George Kodak, had been actioned earlier and plans dating March, 1957 were drawn up for all aspects of the construction. Makaretz Co. was the general contractor; H. Antoniuk, the electrical engineer.

Creaghan and Archibald Ltd, Engineers and Contractors provided the 217 pre-cast floor slabs. Arco Stone, a company founded in 1929, executed the traditional intricate stonework of the pilasters, cornices, and windows in keeping with the intended baroque style as can be seen in the sculpted window frame around the central window, and the tall side windows of the facade.

The Ukrainian baroque church style, sometimes called Kyivan Baroque, is an architectural style that was widespread in the Ukrainian lands in the 17th and 18th centuries – the result of a combination of local architectural traditions and European baroque. This style was well expressed in the structure of St. Basil the Great, Ukrainian Catholic Church making it the subject of the website of notable buildings of Montreal.

Later additions and improvements to the church building between 1971-1983 included the addition of a recreational building and a kitchen. G. Kodak prepared all the necessary architectural drawings for these projects as well, with D. Spencer Eng, certifying them.
