Overnight parking restrictions return to London, Ont. streets after the Labour Day long weekend.

Starting Sept. 4, drivers who require overnight parking will need to register their vehicles, or risk a parking ticket.

Parking will be restricted on city streets between the hours of 3 a.m. and 5 a.m.

The City of London has an overnight parking pass system, which allows drivers to register their vehicles through the city's website, by calling 519-661-4537, or in person at the Parking Services Office, 824 Dundas Street.

A maximum of 15 free passes are available per vehicle license plate.

Between Nov. 1 and Apr. 15, passes are not issued more than 48 hours in advance due to weather concerns. Over the winter months, overnight parking may be restricted to allow for snow clearing operations. In the instance a parking pass is revoked due to weather, a notification will be sent by the city to the registered email address.

Overnight parking passes are required until Victoria Day, when restrictions are lifted.

The fine for parking on a city street between 3 a.m. and 5 a.m. without a permit is $40.
