Both Gyms should be alright. I went to Toronto BJJ when they used to be around Woodbridge area.
Mostly did boxing, some BJJ and a bit of MMA. Judging by website the only striking trainer they got is Dida - i kind of doubt that he participates much.
EDIT: they do have other MT trainer.
Revolution I've read article about, should be professional but needs to be checked out.
Those gyms are in different parts of the city though...
Also check this one out http://www.victoryfightclub.ca/
It's new, lot of space - didn't hear anything great about them but it's up to you to check it out.
Xtreme Couture should be not bad as well...
What do you want to train mostly though?
