There are no pickets up, but the province's DriveTest centre in Fort Frances is closed.
Ontario's driving examiners are on strike after talks aimed at forging a new contract collapsed Friday.
The strike affects people who need to be tested before getting a licence -- not drivers who need a simple renewal.
The province says it is granting automatic extensions for drivers' licences that normally require a test before they are renewed.
About 500 workers represented by the United Steelworkers union are off the job at 55 test centres.
