Many of the tens of thousands of Toronto motorists with overnight on-street parking permits are receiving temporary paper renewals after a city administrative problem.

The same problem also saw renewal notices, telling people to reapply if they want to replace six-month permits expiring Wednesday, mailed out later than usual.

Vince Loffredi, a City of Toronto manager, said temporary renewal permits were mailed last Thursday to motorists who paid for a full year and are automatically mailed the second six-month sticker.

Drivers who bought six-month stickers that are about to expire, and want to renew, should renew them online or in person at city hall and they will get the paper renewals to be cut out and displayed in windshields, he said.

Parking enforcement has been instructed to not give tickets to drivers with expired stickers and no temporary permit until Dec. 12. That shouldn’t affect parking revenues, the city says, because drivers with expired permits normally get a one-week grace period.

Drivers who do not have a permit and are buying one for the first time won’t be affected because those permits are in stock.

The city expects to receive, and send out, the Dec. 1 to May 31 renewal stickers before the end of December.

The city says the problem happened when its staff decided to cross-reference parking information with other city records as part of a review of the permit process, and that took significantly longer than expected.
