St. Michael’s Hospital

Barlo MS Centre

Canada has the highest rate of multiple sclerosis in the world; in fact, the disease is known internationally as 'Canada's Disease'. St. Michael's Hospital in Toronto is one of North America's busiest MS centres. It has been caring for people with MS since 1981, and now treats 7,000 patients.

The new Barlo MS Centre will offer one-stop care, bringing together neurologists, nurses, social workers, neuropsychologists, physiotherapists, occupational therapists and speech therapists in a world-leading treatment and research centre for multiple sclerosis. The 25,000 ft2 clinic will be constructed on the top two floors of the new Peter Gilgan Patient Care Tower.

HH Angus’ mechanical scope for the fitout of the shelled space includes ventilation, plumbing, medical gas, heating & fire protection, and controls. Our electrical scope covers power, lighting, communications and security.

Unique aspects of the project design to date include:  presentation to the client of a number of ventilation strategies to address the shortage of air supply available to the design, and a reworked ventilation strategy under a very aggressive schedule to redistribute and extend air to the clinic from an existing air handling unit that was previously feeding another floor.

Some of the project challenges include:

  1. The addition of a compounding pharmacy late in the design, for which additional requirements had to be vetted to meet NAPRA. The team took advantage of early works to investigate available shaft space for running new biological exhaust to the roof.
  2. Design activities must be scheduled alongside testing and commissioning still underway for the main Patient Care Tower.
  3. Ceiling construction and new structural constraints limited accessibility. The team is using 3D imaging and Revit to coordinate all ceiling elements requiring accessibility, in order to integrate services into areas where wooden slatted ceilings are being used.
  4. The team took advantage of early works to coordinate structural openings for future ventilation in order to limit ceiling interference for the fitout design.

Toronto, Ontario 

Two floor clinic fitout | Variety of room types and functions | Custom smoke venting and fire alarm zoning to accommodate feature staircase

Achieving the design vision

We worked closely with the architect to modify the existing fire alarm zoning and smoke venting strategy in order to accommodate a new mezzanine on Level 17. This will allow the architect to achieve their design vision for the feature staircase without the use of smoke baffles.


Variety of functions

The space will include a variety of room types, including exam rooms, gym, medical infusion centre, group physiotherapy studio, auditorium, cognitive lab and a pharmacy.
