Peel Regional Police officers questioned YouTuber Anthony Sistilli over homemade ALPR deployment tracking service vehicles in Brampton

Sistilli constructed and mounted an ALPR camera that recorded plate reads of Peel cruisers, then published build details and location data on social platforms. Officers arrived to inquire about data retention and intended use, citing risks to personnel safety from location inference. The encounter followed Brampton’s $2 million procurement of commercial Flock systems for municipal surveillance.

ALPR datasets from Flock deployments show retention periods averaging 30 days with access logs often incomplete, per 2023 audits by the Electronic Frontier Foundation and Canadian privacy commissioners. Crime-reduction claims lack controlled studies; a 2022 University of Chicago analysis found no statistically significant drop in auto theft or violent incidents attributable to plate readers alone. Citizen replication exposes asymmetric access where agencies treat equivalent data collection as a threat vector.

Ontario’s PIPEDA and municipal freedom-of-information statutes provide no explicit bar on private ALPR yet require consent or legitimate interest justification. Sistilli’s case illustrates reciprocal surveillance friction: agencies that purchase bulk plate data object when the same capability is pointed back at them. Future complaints filed with the Office of the Privacy Commissioner of Canada could trigger formal guidance on private ALPR within 90 days if volume exceeds prior thresholds.

Operational outcome: police departments will likely accelerate internal policies restricting public discussion of ALPR builds while expanding legal review of citizen-collected plate data under existing mischief or privacy tort statutes.
