I went to Totum for a week while visiting Toronto. Totally satisfied.
The front desk staff was helpful in setting up my one-week membership ($44). They understood that I was only in town for a week and did not try to sell me on any additional products or training sessions. The whole process took less than 5 minutes.
Totum is not a mega-gym. You won't find rows of machines or free weights. However, I did find everything I needed for my workouts (weights and cardio). There are sufficient free weights, two squat racks, a bench, pull-up machine, etc. I never found myself thinking "Hey, I wish they had this machine."
I also loved the atmosphere. Clean interior, classy people, and never crowded. Totum definitely avoids some of the pitfalls of larger public gyms.
I'll definitely use Totum again next time I'm in Toronto.
