331 architectural plans.

The current arrangement of the plans, with some in tubes and others folded in Box 10C, represent an attempt to maintain the original order of the plans as they were filed during the planning of the construction. The plans in Box 10C are bundled with the correspondence that accompanied them. The plans in the tubes were placed there at an unknown point in the past.

On 2025/10/27 the several loose plans were added to the following tubes:

This sub-series contains 331 architectural plans, as well as the planning documentation and correspondance, used in the design and construction of the current church building located at the corner of De Maisonneuve and Claremont. That number represents 60 individual plans, each with between 1 and 9 revisions. The revisions represent the back and forth process between the architects and the Church; as well as between the architects, engineers, contractors and city officials. The plans can be found in the tubes in the archive room, as well as in Box 10C. Box 10C also contains the correspondance between the Church and the architectural, engineering and contracting firms with the relevant plans attached.

Several different firms were responsible for the creation of the plans. Among these the primary architect on the project was Archictem, alternatively identified simply as such or as Architectem Wolff Shapiro Kuskowski. The engineering firm responsible for the project was Nicolet Chartrand Knoll Consulting Engineers. Please see the general note below for a breakdown of the plan designations.
