I highly recommend Spinning Wheels @ Waterloo. They do a thorough and professional job. I take all my cars there.
Make sure you ask for Stuart to do the alignment when you book it. Stuart will even ask what type of driving you do and/or what you'd like to get from the vehicle and he'll align it to that (ie. factory standard, better handling or improved fuel economy or tyre wear etc).
