While there is street parking around Portage Place Shopping Centre, PTE highly recommends parking in the underground parkade at Portage Place itself. It's secure, patrolled and offers easy, direct access to PTE via Elevator A (near the Carlton Street entrance).
It's also one of the most reasonably-priced downtown parking lots - $8 for the evening (compare to $12-$14 around the Concert Hall).
Parking in the Portage Place Parkade:
Simply enter the lot off either Vaughan or Carlton Streets, park and pay before coming upstairs. Your license plate is automatically noted electronically as you enter. There are 12 payment machines throughout the two levels of the parkade (similar to the machines you'd find at outdoor lots). You must buy parking at these machines in advance by entering your license plate number and payment. Note: the machines accept credit cards or exact change only.
You can also pay by phone, using the Secunik app (secunik.com).
