In September 2016, +VG Architects completed the 5 ½ year rehabilitation of the Nave of St. Michael’s Cathedral. The Nave of the Cathedral is the spiritual centre of the Archdiocese of Toronto, a place of beauty and significance for a thriving and diverse Roman Catholic community.

The project aims to re-establish the integrity of the original 1848 Gothic Revival design vision of architect William Thomas, while completing a complete upgrade of the facility in terms of building performance, accessibility and code requirements. +VG was the lead consultant in a collaborative team consisting of a Construction Manager, sub-consultants, sub-trades, artists and craftspeople who completed the work.

New washrooms, barrier-free accessibility (including new barrier-free elevator), environmental HVAC and lighting controls, fire and life safety, and audio/visual and broadcast capabilities have been integrated into the 165 year old Cathedral, ensuring the client’s changing needs are well served into the future.

Painting of the Cathedral ceiling, hand-carved Gothic Revival white oak millwork and statuary, in-situ historic plaster conservation, installation of intricately patterned stone flooring and wainscoting, conservation of existing stained glass windows, and introduction of new stained glass designs, and a hand built custom pipe organ (“Opus-3907”) are all examples of the work completed. The project was recognized with the William Greer Award for Craftsmanship at the Heritage Toronto awards in 2017.
