Where is a good place to start MMA (Mixed Martial Arts) for adult rookies in Canada?

I want to jump and roundhouse kick something like a punching bag…. I’ve been listening to
Double Dragon and I think it might be fun, and good exercise. I would like somewhere were I can loose control and ,“go to town”, on a punching bag. With an inspiring song in the background and for emotional release. Like the good old times in school; fighting bullies and fast thinking, and willpower to be back up.
