CN Tower
Lower Observation Level
The CN Tower's Lower Observation Level was completed and unveiled in January 2026, as part
of the attraction's 50th anniversary celebrations.
The refurbished area comprises 10,600 square feet, including both indoor and outdoor viewing areas, a
glass floor, stairwells, washrooms, and the SkyPod elevator lobby. The project won an IES Toronto Section Award for Excellence in Lighting.
The project was designed to seamlessly extend the recently renovated Main Observation Level 3 aesthetic down to Outdoor Observation Level 2, creating a cohesive and elevated visitor experience.
This renovation marked the first major upgrade to Level 2 since the Tower opened in 1976. HH Angus provided comprehensive mechanical, electrical, lighting, and communications engineering services as part of the transformation.
Mechanical
Scope included the complete refurbishment of existing washrooms, the addition of a new fully accessible washroom, and modifications to the HVAC systems to accommodate the new slatted ceiling design and updated spatial configuration.
Electrical
Work included upgrades to electrical distribution systems and coordination of power requirements for sophisticated new audiovisual installations. LED linear lighting was integrated along the perimeter core walls, and major infrastructure upgrades were implemented to accommodate a future perimeter heated glass system.
Lighting
A new lighting design was developed throughout the space, including exterior colour-changing LED ceiling lighting at the Outdoor Observation Level. Perimeter lighting creates the Tower’s signature exterior glow, enhancing its nighttime presence. Emergency lighting systems were also upgraded as part of the project. The lighting design was recognized with an IES Toronto Section Award of Merit.
Communications
The project included new horizontal cabling infrastructure to support enhanced IT, AV, and security systems. Security enhancements included the deployment of new fixed and PTZ cameras to improve interior and exterior monitoring and support life safety objectives. New fibre optic cabling was installed, along with perimeter Color Kinetics lighting controls that contribute to the Tower’s distinctive exterior illumination.

Balmoral Recreation Centre
Renovation and Expansion
The City of Brampton undertook an extensive revitalization of its existing 53-year old recreation centre.
The project involved a near-total demolition of the existing facility, with the exception of the steel structure of the pool and pool basin. The renovation and expansion have delivered an almost entirely new facility, nearly doubling the size of the former centre to 35,000 ft2. LEED Silver certification is in progress. HH Angus provided mechanical and electrical engineering, ICAT design, and lighting design services.
Key features include the rehabilitated pool, updated change rooms, a multi-sport gymnasium with an Olympic-sized FIBA court (smaller than an NBA court), a sauna, and two multi-purpose rooms that can open to create a more versatile space. The design also incorporates a large, interconnected lobby and administrative offices. Exterior improvements include additional onsite parking, as well as a new outdoor splash pad and playground.
The project replaces all air distribution systems serving the rehabilitated pool and introduces a new high-efficiency condensing boiler system to heat both the pool and the building perimeter. Heat recovery from discharged water is used to preheat incoming cold water for the pool, contributing to the achievement of multiple LEED credits. High-efficiency rooftop units equipped with heat pumps and heat recovery wheels significantly reduce overall energy consumption. Occupancy and CO₂ sensors further optimize performance by ramping mechanical systems up only when spaces are in use. Automatic curtains and daylighting strategies reduce energy demand for interior lighting, while low-flow plumbing fixtures throughout the facility help minimize water usage.

Air Canada
20 Queen Street - Office Fitout
Air Canada’s downtown Toronto office encompasses the entire 26th floor at 20 Queen Street West, with a total area of 20,000 ft2, including the elevator lobby.
For Air Canada's recent renovation, HH Angus provided mechanical and electrical engineering and ICAT design services.
The project featured high-end finishes in the reception area, café, a fully accessible washroom, integrated advanced lighting controls and multiple AC units to enhance occupant comfort and energy efficiency. The result is a modern, high-performance space custom tailored to the client’s needs.

Children's Hospital of Eastern Ontario (CHEO)
Parking Garage
HH Angus is part of the EllisDon Infrastructure team awarded the Design-Build-Finance (DBF) contract for the new CHEO Integrated Treatment Centre (also known as 1Door4Care).
As part of this redevelopment, HH Angus provided mechanical and electrical engineering and fire protection design services for the design of a new 7-storey, 1,050 space parking garage for the hospital which addresses current demand challenges while supporting future growth of the healthcare campus. The new parking garage includes 94 accessible parking spaces and 21 electric vehicle (EV) charging stations.
HH Angus is also providing mechanical engineering services for the design of the new 6-storey, 233,000 ft2 CHEO Integrated Treatment Centre with anticipated completion in Fall 2027.

Canadian Forces Base (CFB) Kingston
Global Adjustment Mitigation & Resiliency Project
The changes resulting from the Global Adjustment mitigation and resiliency project will create additional capacity to support the decarbonization of heating systems, enable electric vehicle charging, and accommodate future growth across the Base.
Delivering multi-phase infrastructure at CFB Kingston required an integrated, adaptive approach to manage evolving scope and interconnected systems. HH Angus executed several related projects:
- Phase 1 – Royal Military College: 3MW Global Adjustment (GA) mitigation generators, with installation in 2025 and completion in 2026
- Phase 2 – McNaughton Barracks: Solar and Battery Energy Storage System (BESS) for power offset and GA reduction; new service entrance switchgear for 2025, with completion in 2026
- Phase 3 – Vimy Barracks: BESS for GA mitigation scheduled for completion in 2026
Under Johnson Control’s Energy Performance Contract, HH Angus was engaged to enhance resiliency and deliver GA savings, beginning with a feasibility study to define optimal solutions. At McNaughton, obsolete switchgear and deteriorated medium-voltage feeders were replaced, along with new solar and BESS systems to reduce peak demand. At Vimy, BESS provides additional demand mitigation.
As scope expanded, HH Angus added replacement of the adjacent Royal Military College’s main 44kV transformers—one having failed—and recommended a second 44kV transformer at Vimy to improve reliability, as prior inter-ties to McNaughton and Utilities Kingston were no longer available.
