What it does: Magna International is a global automotive supplier headquartered in Aurora, Ontario, in the Greater Toronto Area, with operations spanning body exteriors and structures, power and vision systems, seating and complete vehicle manufacturing. Its mechanical engineering teams at Ontario plants design and launch automotive assembly processes, covering tooling, line layouts and production readiness for parts and modules supplied to global automakers. Mechanical engineers at sites such as Milton and Etobicoke work with CAD tools including AutoCAD, SolidWorks and CATIA, interpret GD&T specifications and run PFMEAs, cycle time studies and root cause investigations to improve quality and productivity on automotive production lines.
What it does: MDA Space designs and manufactures robotic systems, satellites and Earth observation technology from its global headquarters in Brampton, Ontario, part of the Greater Toronto Area. The site houses its Space Robotics Centre of Excellence, where mechanical engineers build and test hardware such as Canadarm3, the robotic arm system developed for lunar operations, alongside components for satellite systems used in programs like the RADARSAT Constellation Mission. Mechanical engineering teams there work on structural design, assembly and vibration testing for spacecraft and robotic hardware that must withstand launch and operate in orbit, supporting MDA Space’s broader satellite systems and robotics manufacturing divisions.
What it does: Tesla operates its Tesla Toronto Automation team out of the Greater Toronto Area, with engineering sites in Richmond Hill and Markham, Ontario. The team designs, builds and services custom high-speed, continuous-motion manufacturing equipment used across Tesla’s factories worldwide. Mechanical engineers on this team work across the full product lifecycle, collaborating with design, process, manufacturing, quality and controls groups to conceptualize new equipment, troubleshoot design issues and improve machine performance. Open roles have included staff and senior mechanical design engineers, CAD mechanical designers and mechanical engineering interns, reflecting ongoing hiring for hands-on mechanical design and automation equipment work in the Toronto area.
What it does: Thornhill Medical designs and manufactures portable medical devices for military, emergency and field hospital use from its Toronto facility on Wingold Avenue. Its flagship product, the MOVES SLC, combines a ventilator, oxygen concentrator, suction and vital signs monitoring into a single battery-powered unit, and the company handles final assembly and end-testing in house rather than outsourcing to contract manufacturers. That approach requires an internal mechanical engineering team to support product design, prototyping and manufacturing processes, and Thornhill Medical hires for manufacturing and engineering roles at its Toronto headquarters as it builds out devices used by military and first responder teams worldwide.
What it does: Kepler designs, manufactures and operates satellites in-house at its Toronto headquarters, where it runs a production facility spanning 30,000 square feet for assembly, testing and operations. Its mechanical engineering organization covers mechanical design, structures, thermal systems and mechanisms, with engineers leading spacecraft subsystem development from concept through production and supporting scalable manufacturing processes. Kepler’s mechanical project engineers work across CAD, structural and thermal design while coordinating with systems, software and quality teams on spacecraft builds. The company has launched over 20 satellites to date and continues expanding its Toronto-based manufacturing capabilities to support mass production of its next generation of spacecraft.
What it does: Multimatic is a privately held automotive supplier headquartered in Markham, near Toronto, that engineers and manufactures complex mechanisms, body hardware, suspension systems and body structures for global automakers. Its mechanical engineering teams work across design, structures and suspension, covering CAD modeling, GD&T drawings, DFMEA and tolerance stack-up analysis as components move from concept through high-volume production. The company hires mechanical engineers for roles such as design engineer and structures engineer at its Markham facilities, where engineers collaborate with manufacturing, quality and OEM customers to validate parts through prototyping and testing before launch.
What it does: Myant Inc., headquartered in Toronto, designs and manufactures smart textile products through its Textile Computing platform, including the Skiin line of connected garments for continuous health monitoring. Founded in 2010, the company builds its wearable and sensing hardware at its Toronto facility, where teams develop conductive yarns, miniaturized electronics and textile-integrated sensors in house. Its mechanical engineering group leads mechanical design and prototyping for these wearable platforms, working with 3D CAD tools such as SolidWorks, and manages the transition from prototype to manufacturable production, including supplier coordination for injection-molded components used in its devices.
What it does: Bombardier designs and manufactures business jets, including its Challenger and Global aircraft families, with production and engineering work spanning multiple sites in Canada, including a Toronto assembly facility alongside its Quebec plants. Its mechanical engineers support structural and systems installation design, door and mechanism design, and hydromechanical systems, performing mechanical design work in CATIA V5 and providing technical support across the multi-site assembly line that includes Toronto. Bombardier has posted mechanical engineering roles requiring degrees in mechanical or aerospace engineering, covering aircraft structure, systems installation and interiors work tied directly to its business jet manufacturing programs.
What it does: Honeywell Aerospace develops and manufactures aircraft systems and components out of its Mississauga facility in the Toronto area, including air and thermal systems, and mechanical components for commercial and military aircraft. Its mechanical engineering team designs and sustains hardware such as electrical power, environmental control and sensor systems, handling tasks from materials obsolescence fixes to nonconforming parts resolution and product qualification. The company has hired for roles including senior advanced mechanical design engineer and mechanical engineering intern positions, with engineers collaborating across global design centers and factories to support products already in production.
What it does: Curtiss-Wright Corporation designs and manufactures highly engineered mechanical and electro-mechanical components for aerospace, defense and industrial customers, with Ontario operations highlighted by its Indal facility in Mississauga supporting its naval and defense systems divisions. Mechanical engineers on its teams work on product development tasks such as 3D modeling, prototyping, FEA analysis and design for manufacturability, then carry designs through testing, validation and production support alongside manufacturing and supplier teams. The company’s Canadian manufacturing capability also lets it produce actuation and sensor hardware domestically to meet Canadian government program requirements, giving its mechanical engineering staff direct involvement in both design and build processes for regulated, safety-critical equipment.
