Best mechanic

I own a 2000 Montana that has been running great, since I bought it, but I know that sooner than later I will have to take it to the shop for a tune up or some other repair, I live in Toronto and I will like to know if any of you can recommend a good shop here, that have a fair price and also do the proper job, maybe we can even get a deal with a particular shop where all of the Automotive Forums members can go and get even a better price.
Thanks
