Ontario Tech acknowledges the lands and people of the Mississaugas of Scugog Island First Nation.

We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Large Climatic Chamber

This chamber is unique due to its exceptionally long test section, which accommodates vehicles as large as an articulated buses. It also contains a Mustang 1,000 horse-power chassis dynamometer and a solar array to simulate the sun. You also have the option of connecting to the small climate chamber through an inter-chamber door, which permits the insertion of a test bench to effect a 'three-chamber' mode that includes:

  • climatic wind tunnel
  • large climate chamber
  • small climate chamber


A vast number of sectors can utilize ACE’s climatic chambers. Any product, component or idea that needs climatic validation or testing will find significant value in this chamber.

Testing examples:

  • cold or hot starts for vehicles
  • engine tuning (on Mustang dynamometer)
  • heating, ventilation and air-conditioning (HVAC) testing
  • physiological/cognitive human trial tests
  • product validation in extreme temperatures or solar conditions
