Huge thank you to Ontario Tech University !!! for the awesome invite to tour the ACE (Automotive Centre of Excellence) Wind Tunnel! 🌬️😎

We got a behind-the-scenes look at one of the most advanced climatic wind tunnels in North America and learned how they recreate wild weather—wind, rain, snow, and extreme temps ❄️🌧️🌪️—for real-world testing.

Such a cool experience and an incredible facility! 🙌🔥

J.J. McGuire was proud to once again participate in the Women in STEM initiative at Ontario Tech University 🎓✨

The mission is clear and meaningful: to see more women entering engineering and STEM programs 👩‍🔬👷‍♀️💡 It was inspiring to meet so many driven young women who are ready to shape the future!

Hosted at the ACE Climatic Wind Tunnel, the event reinforced the importance of continuing to support and empower the next generation of women in engineering 🚀

If you know a young woman interested in STEM, encourage her to explore the possibilities 💙
