GO Transit recently opened a new temporary parking lot with 175 spaces on the south side of Bronte GO Station.
You can drive into this lot from Speers Road. The lot has a temporary walkway to give you access to the south platform and ticket-canceling machines. Unfortunately, you can only reach the PRESTO card readers from the north platform, if you use a PRESTO card to pay your GO fare.
This temporary lot remains open until GO opens its the new permanent lot with 300 parking spaces this summer.
