Greenhouse Gas Reduction and Resilience Action Plan
HHSC asked HH Angus to develop a strategic and comprehensive GHG Reduction and Resilience Action Plan to guide HHSC in meeting provincial and federal greenhouse gas reduction targets for 2030 and, eventually, "Net Zero" by 2050.
The scope of the work HH Angus provided covered the following HHSC sites (totaling approximately 3,200,000 ft2):
- McMaster Children’s Hospital
- Juravinski Hospital and Cancer Centre
- Hamilton General Hospital
- West Lincoln Memorial Hospital
- St. Peter’s Hospital
- Ron Joyce Children Health Centre
- David Braley Research Building
HH Angus developed a Strategic GHG Reduction and Resilience Action Plan (GRRAP) for HHSC to support their goal of achieving carbon neutrality by 2050. This plan included establishing a GHG inventory for Scopes 1 and 2, in addition to forecasting future emissions. (Scope 1 emissions include direct emissions from on-site combustion, and have consistently represented the majority of total emissions. Scope 2 emissions are associated with purchased electricity, steam and/or chilled water.)
GHG reduction targets were set in alignment with leading international frameworks such as the SDGs (sustainable development goals), SBTi (science-based targets initiative), and UNGC (UN Global Compact).
Some key considerations in developing the GRRAP included:
- Aging infrastructure and deferred maintenance
- Emissions from natural gas combustion
- Carbon tax financial risk
- Integration of redevelopment with decarbonization
- Uncertainty in future district energy and waste heat
- Embedding Equity, Diversity and Inclusion and sustainability culture
HH Angus completed an analysis of existing energy and sustainability plans, policies, and facility assessments to identify key opportunities for GHG reduction, while adhering to GHG Protocol standards. The newly created GRRAP document outlined the necessary steps, measures, infrastructure requirements, and financial scenarios needed to meet or exceed the proposed GHG reduction targets.
The implementation plan focused on energy conservation, electrification, renewable energy generation, and zero-carbon building solutions. Additionally, HH Angus provided HHSC with a GHG Manager tool to facilitate ongoing scenario modeling.

MECP-MLITSD Science Facility Complex
The new complex will bring together existing operations into a single, modern, science and laboratory facility that will strengthen capacity to deliver on critical mandates of protecting the environment, public health, and safety.
The new Science Facility Complex will permanently replace Ontario's Ministry of the Environment, Conservation and Parks’ (MECP) facility at 125 Resources Road and Ministry of Labour, Immigration, Training and Skills Development’s (MLITSD) temporary facility at 6295 Northam Drive (formerly at 81A Resources Road).
HH Angus’ Science and Technology team is providing compliance (PDC) engineering services for this Design-Build-Finance-Maintain (DBFM) infrastructure project that will protect public health and the environment through advanced monitoring of radiological materials, environmental contaminants, and live viruses. The new facility will have purpose-built, flexible design to allow for adaptable laboratories, science workshop spaces, and offices to support both current operations and future growth.

Nathan Phillips Square Spirit Garden
The Spirit Garden in Nathan Phillips Square — recipient of the 2025 Canadian Wood Council Wood Design & Building Award, as well as an Award of Excellence from the Toronto Urban Design Awards — is part of the City’s revitalization of its landmark civic space at New City Hall. As part of the improvements, a new Teaching, Learning, Sharing, and Healing space was designed and constructed to recognize and honour the experience of Indian Residential School Survivors.
The project consisted of upgrades to existing surfaces with all new landscaping, including a water feature, large sculpture and public building.
HH Angus’ scope of work included mechanical and electrical engineering, security systems consulting, IMIT design, and commissioning. Specifically, the scope featured a full technical audit and inventory report to document all infrastructure and equipment impacted by the project; power supply for new landscape and other LED lighting fixtures; connection of new area drainage to existing storm systems in the parking level; mechanical and electrical services for the new 450 ft2 Teaching Lodge; and design of security systems for public spaces and the Teaching Lodge.
HH Angus also developed and prepared a commissioning plan for all mechanical and electrical equipment being installed during the project.
One of the interesting challenges of this project was working with multiple stakeholders to ensure the vision of all parties for the project was addressed.

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.

Thunder Bay Correctional Complex (TBCC)
The TBCC involves replacement of aging jail and correctional facilities with a new 345-bed, multipurpose complex. Both the existing Thunder Bay Jail and Thunder Bay Correctional Facility are among the oldest provincially-run adult correctional facilities, built in 1928 and 1965 respectively.
The new TBCC updates automation and technology to address issues of health, safety and security, and introduces efficiencies around design, technology, and the use of space. HH Angus is providing mechanical consulting engineering and vertical transportation consulting to the EllisDon Infrastructure Justice design team.
The TBCC is targeting LEED Silver certification and LEED Resilient Design pilot credits through the United States Green Building Council. The design focuses on energy efficiency, healthy indoor environments and reduced greenhouse gas emissions. The complex will also include views of nature, allow ample natural light and feature dedicated Indigenous cultural spaces, such as smudging space and sweat and teaching lodges.
The new facility is the first of its kind for an Ontario correctional facility, incorporating design features that promote rehabilitation of inmates. It will also improve access to programming, living conditions and education, while updating automation and technology.
The TBCC project has presented several challenges to our design team, including a compressed schedule and the involvement of numerous stakeholders. It has also been interesting on a technical level: mechanically, the various modes of operation and interconnection of systems are quite complex, necessitating a high degree of flexibility within the capacity of the mechanical equipment. The building construction featured a precast exterior with block walls, requiring very close coordination with trades to align openings and allow access for equipment.
Due to the secure nature of the facility, the mechanical system was integrated seamlessly into the architectural features, all accessible equipment is provided in a secure location, and all building systems interact
with the BAS.
The facility will include a connection to an existing 50-inmate facility — the Thunder Bay Modular Built Facility — located southeast of the TBCC and currently under construction. The project also involves the design and construction of a 4,000 ft2 wastewater treatment facility to allow for a fully self-sufficient and self-contained facility.
