Welcome to Threshold Headquarters

Take care of your body. Its the only place you have to live.

At Threshold Headquarters, our approach is what makes us the best value in Ontario and we have proudly continued that philosophy since. We asked ourselves what is vitally important to our clients, and we arrived at a method that is efficient and effective. It doesn’t matter if you have never worked out before or are just ready to take it to the next level. At Threshold Headquarters, we will help you get where you want to go. We want everyone to come and feel at home when they train at our facility!
