Security guard and private investigator basic testing

As part of a pilot project to evaluate a new online security guard testing service, a small group of individuals who are scheduled to write their security guard test in person will be offered the opportunity to write their test online in English starting October 20, 2020. Individuals will be selected from areas with the most scheduled tests.

This is part of Ontario’s plan to launch online testing for security guards across the province later this fall. Online testing for private investigators and test services in French will be launched at a later date.

For more information, please visit Serco’s website or contact Serco at

There are separate basic tests for security guards and private investigators.

Tests consist of 60 multiple-choice questions based on topics covered in basic training courses. You will have 75 minutes to complete each test.

Please note that in order to register for a test, you will need a training completion number from your basic training course provider.

Tests are offered at select DriveTest centres across Ontario.
