Car2Go is a fantastic car sharing company that has just recently come to Toronto. My husband and I used Car2Go when we were living in Austin, and it it the best car sharing service out there (we've tried others). The main advantage over other car sharing services is that you can drop the car off anywhere within the home area, not just in a designated Car2Go space or (as is the case with other car sharing companies) only in the space you picked it up from. They have a promotion on now so you can get free registration and 30 min of free drive time by entering promo code TDOT when you register. Happy car sharing!
