About Us

30 Years

Monster Gym is one of Montreal’s premiere fitness centres and has serviced its members for 30 years!

A leader in the health community, our family-owned business has grown from a small, 8000-square-foot gym to over 70,000-square-feet and we’re still getting bigger. Its empty shell measured 8000 square feet, had no air conditioning, no cardio equipment, and no fitness studio or classes. While we’ve grown from our humble beginnings to become the largest gym on the West Island, we’re as committed as ever to giving our customers that family vibe they’ve come to expect from Monster.

Monster Gym remains one of the only fitness centres in Canada open 24/7. With state-of-the-art equipment and specialized training available for everyone from beginners to body-building experts, there’s no reason for you to put off getting fit. Life’s better when you work out.


Even with all this growth, we have made it a priority to ensure that the feel and vibe of the gym is and will always be inviting and friendly; we believe that working out should be available to everyone. We follow the three golden rules in the gym business:

  1. Cleanliness
  2. Equipment for everyone’s needs
  3. Staff to serve in a friendly and professional way

Monster is, at its core, a family, and we want to keep it that way. That commitment to our customers extends to helping the community as well. Monster Gym is proud to support multiple local and national charities.

With the most high-end equipment,  and the most hours in Montreal, Monster Gym doesn’t just set the bar. Monster is the bar.

  • Monster Gym is by far the best gym to workout. It’s open 24 hours a day, has a vast array of every gym equipment imaginable and a running track, sauna, and a swimming pool as well. The staff are friendly and the gym is immaculate and modern. There is even a great restaurant and shake bar called Bistro Fit. You literally have everything you can ever need under one roof.
