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.

City of Mississauga

Burnhamthorpe Community Centre Renovation and Expansion

The Community Centre features a state-of-the-art aquatic centre as well as an equipment-based fitness centre. This is the first project designed and built to Mississauga's corporate Green Building standard. The project has also achieved Level 1 CGBS and incorporates net zero and passive house principles, a high-performance building envelope, triple glazing, and a green roof.

HH Angus played a key role in this project, providing mechanical and electrical engineering services, as well as security, IMIT, lighting, AV, and plumbing design. The addition includes a new 25-metre, 6-lane pool, therapeutic pool, fitness centre, and common areas, for a total of 43,000 ft2 of added amenities.

Renovations to the existing community centre encompass improvements across 65,000 ft2, repurposing and relocating multi-purpose program spaces, gymnasium, indoor arena, and upgrading facilities to meet accessibility and green development standards. Despite challenges posed in connecting to the existing building, the addition was situated on the northeast corner, utilizing space from the adjacent park.

BMO Field Expansion

HH Angus and Associates provided mechanical and electrical consulting engineering for renovations to BMO Field. Home to the TFC, Toronto’s MLS football team, the existing facility quickly outgrew its amenities, a testament to the team’s popularity.

The BMO Field facility expansion featured: 8,400 additional seats, new washrooms and concession stands; 12 new executive suites; 2 party suites; a loge box; new full-service kitchen for restaurants, suites and clubs; 2 new private clubs (accommodating 230 / 420 patrons); expansion of the Rogers Club from 500 to 750 patrons, plus upgraded finishes and improved food, beverage and washroom facilities; a new, larger full HD video board; new loading dock; support spaces; and a new concourse at the south end of the stadium, creating one continuous concourse on the upper level. The project was drafted in REVIT, although it is not a true BIM project.

Some of the project challenges included coordination of the design package with the realities of site constraints and energy goals. HH Angus had dealt with these challenges in the past and had a depth of experience in Construction Management, P3, and Integrated Project Delivery methods, as well as having a firm grasp of the complexities associated with coordinating the design across multiple Revit models and with multiple firms.

The accelerated construction schedule presented a significant challenge. Work that traditionally occurs sequentially had to be delivered concurrently, which put pressure on the design team to accommodate not only increased coordination, but also a high number of changes from the original design intent.

One of the unique engineering considerations was the winterization of washrooms and concession areas. These areas are exposed directly to the elements during the winter and the facility management team did not want to drain the domestic system at the end of every season, as they had to do with the existing concourse areas.

Queen’s University

Richardson Stadium Revitalization

HH Angus has a long and valuable relationship with Queen’s University, covering numerous projects across a range of buildings and services at the campus, including new build, renovations, expansions and district energy scopes of service.

In 2014, Queen’s began a revitalization of its premier sports facility, Richardson Stadium, and engaged HH Angus to provide mechanical and electrical engineering to the Revitalization project.

Our scope of work included mechanical and electrical design for the new East Building and renovated West Building; and electrical power design for the East and West Buildings, plus field lighting.

The Stadium work was executed in two phases: Phase One was the Feasibility Study and Phase Two covered the project implementation. To launch Phase One, system options and minimal requirements were confirmed with the University’s Facilities team in Kingston. There was also a series of meetings with the Construction Manager and primary trades to confirm the basis of the original estimates and to discuss the impact of system options.

Phase Two incorporated a value engineering exercise to develop alternative project phasing plans to maintain the budget. A final mechanical and electrical Schematic Design report was prepared following the value engineering exercise. Under Phase Two, HH Angus was retained to carry the project through from Design Development to Construction Administration.
