Opercule Urban Fish Farm
The Opercule Fish Farm project is a pioneering initiative in the heart of Montreal, representing the first urban fish farm in Canada. This innovative project is based on a unique approach to fresh fish production, combining cutting-edge technology, respect for the environment and a local supply network.
Opercule annually raises 25 to 30 tonnes of Arctic Char, a fish species highly prized by Montreal restaurants and residents, and raised without the use of chemicals, hormones or antibiotics.
The primary goal for the Opercule Fish Farm was to create an eco-friendly, sustainable fish farm with a low impact on the environment and providing excellent living conditions for fish. HH Angus worked closely with the client to understand their unique and ground-breaking vision and was able to design innovative solutions tailored to this one-of-a-kind project. The project’s design also stands out for its ability to produce fresh fish locally in a non-coastal city.
This model of aquatic urbanism fits perfectly into a context where demand for local, sustainable products is growing. Working with the HH Angus design and engineering team, Opercule is meeting Montreal’s appetite for Arctic Char by supplying top-quality fish while reducing the usual carbon footprint associated with transporting seafood from coastal regions.
The project's innovative design and short-supply chain production model allow Opercule to raise high-quality fish in an urban environment in response to a growing local demand for sustainable food products. Fish swimming in the morning can be on diners’ plates the same evening, frequently delivered to restaurants by e-bikes to further reduce the product’s carbon footprint.

KEY SCOPE ELEMENTS
Design and engineering to enable production of food fish in a dense urban environment, utilizing municipal services infrastructure| Production of technical reports for provincial Authorities Having Jurisdiction, due to uniqueness of the project | Custom design solutions to respond to changing operational conditions
Enabling production at scale
No design references or construction expertise existed for this pioneering enterprise, and the client placed their trust in HH Angus’ ingenuity and adaptability to deliver the vision.
The project’s key technical innovation was the development of the Recirculating Aquaculture System (RAS) system - the first of its kind in Quebec - which allows fish to be produced in a closed circuit, from egg to table.
From the outset, we worked very closely with Opercule to thoroughly understand the challenges and goals. The client had a strong vision for their new company, were deeply committed to its success, and actively involved in the project’s technical aspects. One of the owners brought a background in consulting engineering, and this made our collaboration highly productive.
Reducing environmental impact
The primary goal for Opercule was to create an eco-friendly, sustainable fish farm with a low impact on the environment and providing excellent living conditions for fish.
The RAS process is a sustainable model that significantly reduces the environmental footprint of the operation by reducing not only water but alsoenergy consumption compared to traditional aquaculture. The system minimizes the use of these precious resources, a crucial factor in an urban environment. By recovering, filtering and reusing water, the farm significantly reduces water consumption compared to traditional fish farming methods, which are often very water intensive. The system allows the company to reduce water consumption by 100 – 200 times compared to traditional systems.
In terms of waste management, Opercule uses environmentally friendly techniques to treat the organic and biological waste generated by production, helping to reduce overall environmental impact. The project also promotes use of sustainable materials for the construction and fitout of the facilities, reducing the carbon footprint of the entire system.
In addition, the absence of chemicals, hormones and antibiotics in fish production ensures no soil or water contamination. This approach helps preserve local ecosystems and eliminates the risk of pollution.
Engineering design challenges
The complexity of the Opercule project stems from a number of technical and logistical factors. The creation of an urban fish farm requires a completely unique design adapted to a dense urban environment. The design of a water recirculation system, intended to ensure the well-being of the product from the egg stage to the delivery of the fish, required the development and refinement of innovative technologies in filtration, nutrient management, and optimization of living conditions in confined environments.
Challenges included managing water quality, which is essential for fish health, as well as creating an optimal environment for rearing Arctic Char, known to be a delicate species. This challenge involved the creation of autonomous systems to maintain constant temperatures and pH levels, without the need for chemical treatments. In addition, bio-safety management was a priority to avoid contamination.
During the operational phase, it was discovered that the heat generated by the fish—even though they are cold-blooded—had been underestimated. This required adjustments to operational conditions to maintain stable water temperatures. Despite this challenge, our close collaboration with the client ensured these modifications were implemented effectively, showcasing the team’s problem-solving abilities.

Michael Garron Hospital
Patient Care Centre ICAT Strategy
HH Angus was engaged as part of the Compliance team for the new eight-storey Patient Care Centre at Michael Garron Hospital (MGH), formerly Toronto East General.
The project also included a three-storey connection, as well as demolition and renovations to the existing hospital. MGH is a large community hospital serving the diverse Toronto community of East York. Many of the buildings are old, some dating from 1927.
Angus Connect assisted in developing a long term IT strategic vision for the Hospital, including directions, gap analysis, strategic recommendations and Information Technology (IT) solution options for IT to support the hospital moving forward. The Hospital aimed to achieve EMRAM level 7, the highest level in becoming a paperless and digital facility. It also looked to identify automation opportunities to become a smarter hospital. Angus Connect fulfilled the Compliance role for the Hospital, preparing the PSOS for ICAT systems and integration requirements in integration matrix and interoperability use case definition.
The new Patient Care Centre redevelopment was the first phase in the master plan for the site, addressing the highest priorities – namely, consolidated facilities for outpatient services, replacement of inpatient beds in older wings, and several related non-clinical areas. The Redevelopment adds approximately 550,000 ft2, including a new tower to house inpatient and mental health beds, ambulatory clinics and a new underground parkade. It also included approximately 100,000 ft2 of renovation within the existing facility, including a Cardiac Catheterization Suite and administrative areas. The project has been certified LEED v4 BD+C Silver.
As the Angus Connect team developed the technical output specifications, they reviewed options for phasing and system integration. Design standards and technical guidelines, incorporation of operations, life cycle and maintainability requirements are of the utmost importance for this project, as the facilities’ operation and maintenance became the responsibility of the Hospital upon completion of construction.
