This October, the WOWC and Trillium Network team up to shine a spotlight on southwestern Ontario manufacturers

October is #ManufacturingMonth. To mark this important month, we’ve teamed up with the Western Ontario Wardens’ Caucus to showcase a series of innovative Ontario manufacturers from Essex to Simcoe Counties (and everywhere in between).

These companies manufacture everything from agricultural technologies to ice cream to machines used to build electric vehicles. They make important contributions to their local communities and to the province’s economy and innovation ecosystem. 

Many of these companies are hiring. If you are interested in a career in manufacturing, make sure you stay tuned throughout the month to learn more.
