Traffic Operations Centre & MERO

The Traffic Operations Centre and MERO Laboratory, completed in two phases on the new COMPASS campus in Toronto, was carefully designed to improve the efficiency for traffic management services in Toronto and surrounding municipalities. mcCallumSather and Kasian teamed on the project. Our primary objective was to shape an environment that supported and enhanced its staff’s ability to deliver these essential services, including its team’s critical research.

The award-winning, LEED Silver Certified Traffic Operations Centre, completed in 2016, was completed on a fast-tracked timeline, first serving as the security hub for the PanAm Games. The building is divided into zones, organized by employee function. It includes a modular, flexible layout for the workshop, labs and warehouse; an open plan with transparent offices for administration; the latest in security and automated design; and state of the art AV for easy communication and collaboration. High security is carefully balanced with an open and welcoming space.

mcCallumSather was primarily involved in the design of its innovative building enclosures and exteriors on the two projects.  The high performing building envelopes were critical to our client’s sustainability objectives. The barrier-free campus features extensive canopied entrance vestibules for rain and snow protection; passive solar shading at the south facade and an accessible green roof. We followed Toronto Green Standards, and took special care to make sure the campus was as bird-friendly as possible. This includes lowered exterior lighting levels and a strategy to reduce nighttime ‘light traps’. To reduce the reflection and optics of transparency, we treated the exterior glazing with fritted glass.  It maximizes access to natural light and screens its occupants from direct exterior view. Additionally, we chose a palette of natural materials that provided above-normal acoustics values.

Within the MERO building, completed in 2020, is a three-storey laboratory building designed for research and testing essential to the Ministry’s ability to set material standards, policies, guidelines and specialized laboratory testing. The space includes laboratories, workshops, administrative and workspace, and specialized garage specifically designed to store and test its fleet of vehicles.
