Although I'm a big fan of the GO Train, I found Clarkson GO Station a bit challenging to navigate. It's a large station with an extensive parking area. I had a hard time locating the screen that displays the train platform numbers, as it's situated in the basement of the parking building.
The parking structure is large and free with wheelchair accessible amenities, I.e. elevator...nI have never had a problem finding a parking spot and when I leave it still has many spaces available. Be careful to not park in a reserved spot, most of the outdoor spots are reserved.
Bike theft! While the GO train staff are amazing, lost my bike chain-locked to a designated bike parking space. Filed a report...no response...hopeless lack of cameras. I forgot to bring my U-lock that day so beware cyclists!
Lots of parking. I found it to be one of the better spots to get on the go train. About 37 minutes to Union Station. Clean.nParking available on both sides of the tracks. Biggest lot is on the south side
Loads of free parking. Clean station. Conveniently located.
