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 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.
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.

Confidential Client
Quebec Data Centre
HH Angus provided comprehensive engineering services for the design, development, and implementation of a state-of-the-art data centre.
HH Angus was responsible for the design of the facility’s mechanical, plumbing, lighting, fire protection and building environmental control systems. This facility is split into critical and non-critical areas. The critical areas included mechanical and electrical rooms housing equipment supporting the main server spaces. The non-critical areas included administrative spaces such as meeting rooms, open offices, telecommunication service entry rooms, technical spaces housing servers supporting site operations, and a loading dock. Beyond the footprint of this building, our scope of services also extended to ancillary site structures such as the main gate guardhouse, water treatment buildings, fire pump buildings, and the deployment of private weather stations.
HH Angus implemented an evaporative cooling system to support critical IT servers. Our team designed a water treatment facility and rainwater harvesting system with a detailed metering scheme, giving the Owner visibility into water use. This made the facility water-neutral and self-sufficient year-round, eliminating reliance on municipal water for cooling.

The Co-operators Calgary
Tenant Fitout
This project focused on a tenant renovation of two floors in The Co-operators' newly-acquired downtown Calgary office space, and comprised 40,000 square feet. The project has been certified WELL Gold.
Our approach included early coordination with the landlord to ensure handover conditions suited the client’s requirements, as well as close coordination with the construction manager in creating a pre-order due to a condensed construction schedule.
The construction schedule was a key challenge of the project along with the timing of tender. The completion date was an unmovable milestone as the client’s lease was expiring at their other location. At time of tender, product and material availability were fluctuating, which created uncertainty around delivery. To meet the deadline, our team was tasked to do everything possible to ensure the success of the project and keep the schedule on track.
To help ensure timely delivery, our team incorporated a pre-order package for the construction manager to tender, which allowed products to be reviewed and released ahead of the official tender. This effort was successful and was completed according to plan; however, some delivery delays were unavoidable, due to market conditions. To mitigate the impact, we were then tasked with contacting industry partners to help expedite deliveries. In addition, alternative temporary designs were implemented to ensure the move-in date could be met by planning the switchover date once the outstanding equipment arrived.
The Calgary office marks our fifth tenant improvement project for The Co-operators, following similar fitouts for their locations in Guelph ON and Regina SK, as well as pilot projects in Montreal QC and Burlington ON.

Waypoint Centre for Mental Health Care
Chigamik Community Health Hub
Waypoint Chigamik Mental Health Centre is part of a redevelopment project and replaces two older facilities in use since the 1800s.
The challenges of this project included the requirement that the entire building be completely designed in one stage, rather than proceeding with design packages, plus delays in funding during the design process which resulted in a requirement for both a base building package and a fitout package.
To accomplish this, HH Angus coordinated two tender packages and two building permit submissions. Some detailed specifications in each package were interchangeable for the mechanical and electrical tender process. Working with phased schedules ensured that equipment start-up was fully coordinated between the tender packages.
The project faced additional challenges to provide an energy-efficient HVAC system, due to compliance with CSA Z317.2 and budget restrictions, as well as a small mechanical service space. To overcome these challenges, extensive coordination was implemented throughout the project across all disciplines.
