Automated License Plate Reader (ALPR)

Automated License Plate Reader (ALPR) technology, also known as License Plate recognition, provides automated detection of vehicle license plates. An ALPR is used by Bylaw Enforcement Officer’s to monitor vehicles that are parked within time restricted zones and have stayed beyond the posted time limit.


What are the benefits of using an APLR?

An ALPR replaces the manual process of chalking a vehicle and collecting evidence. The automated system reduces staff time and improves efficiency in monitoring timed parking zones.

Where are time restricted zones located?

Time restricted zones can be located on streets or within municipal lots and are signed indicating a time restriction for the corresponding location.

How does an ALPR work?

How does an ALPR work

  • An APLR system, which is mounted on a bylaw vehicle, drives by vehicles parked within a time restricted zone
  • The APLR system automatically captures an image of a vehicle's license plate
  • Wheel imaging cameras digitally chalk a vehicle, collecting evidence (photo and gps coordinates) for future follow up
  • Upon a follow up drive through of the time restricted zone, the APLR will identify and alert a bylaw officer of a violation
  • A bylaw officer may enforce a violation by issuing a bylaw offence notice


The automated license plate reader collects personal information in accordance as permitted under Section 26 of the Freedom of Information and Protection of Privacy Act (FIPPA). Only staff with the authority to access the information will have access for ticketing purposes.
