TORONTO - DriveTest will open four more centres for limited services beginning Monday, bringing the number of centres open in Ontario to 12.

DriveTest had originally opened six centres using only management employees and is expanding this number using a mix of management employees and striking employees who have returned to work.

The new centres opening Monday will be Kingston, St. Catharines, Bancroft and Ottawa Walkley Road.

Centres previously opened are Barrie and Chatham, Ottawa Canotek, Kitchener, North Bay, Thunder Bay, Brampton and Toronto Port Union.

The only services provided will be written tests for all classes of licence, road tests for commercial classified licences and out-of-province and out-of-country licence exchanges.

The strike affects 93 full-time and part-time DriveTest sites, which grant or renew licenses to novice drivers and those over 80.
