I love taking the GO train, its very clean and comfortable. Its a smooth ride and is convenient to get you where you need to go. Way better than going places and having to find a parking spot. If you're in Toronto and there is a downtown event,like the CNE, you'll never find a spot to park down there (unless you wana pay alot), so this is a good (though maybe crowded at peak hours) option. It can sometimes be a bit pricy though.
