McIvor Construction Management completed a phased interior renovation at St. Catherine of Siena Church in Mississauga, modernizing key spaces while maintaining full building operations throughout construction. The project focused on enhancing functionality, updating finishes, and creating a refreshed, welcoming environment for parishioners.
Working within an active place of worship required careful coordination, respectful scheduling, and close communication to ensure services and daily activities continued uninterrupted.

All work was executed in phases to accommodate ongoing church services and community programming. The basement bathrooms and main church areas were renovated sequentially, allowing spaces to remain accessible while improvements progressed.
This staged approach required detailed planning and trade coordination to maintain safety, cleanliness, and minimal disruption to staff and visitors.
The scope included new finishes throughout, updated basement washrooms, and improvements to key architectural elements within the sanctuary. A standout feature of the project was the installation of a new feature wall at the altar, creating a refined focal point that enhances the visual presence of the space.
New confession booths and upgraded interior finishes contributed to a cohesive, contemporary design while respecting the character and purpose of the church.

Renovating an occupied institutional building presented logistical and scheduling challenges, but proactive planning and consistent communication allowed the team to overcome obstacles efficiently.
The result is a modernized, durable space designed to serve the parish community for decades to come, delivered with the quality and care expected of McIvor CM.
