A Montreal-based lawyer, identified only as Alexandra to protect her professional reputation, was flagged as a nationwide public safety concern after an incident at the Riverside bar in Winnipeg's St. Vital neighbourhood on June 6. Security staff scanned her driver's licence using a Patronscan system without explaining the process. Later that evening she felt unwell, entered the nearest washroom, and was asked to leave after someone knocked on the door. She departed without further incident. On July 9 at a Calgary Stampede venue using the same system she was refused entry and told she had a criminal record, which was untrue. The flag, visible only when her ID was scanned, described her as a 'public safety concern' of 'serious' severity for allegedly entering the men's washroom and refusing to leave at the Riverside. The venue in Alberta could see the Winnipeg incident because both establishments participate in Patronscan's flag network, which shares details of problematic patrons across North America and beyond to prevent dangerous individuals from entering venues. The Riverside manager later acknowledged the external flag was a mistake that should have remained internal only. The bar removed the flag, reviewed staff procedures on when information should be shared, and emphasised the distinction between legitimate public-safety use of the system and this administrative error. Privacy experts, including University of Ottawa professor Teresa Scassa and former Ontario privacy commissioner Ann Cavoukian, raised concerns that federal private-sector privacy rules require meaningful notice of the purposes for collecting and sharing personal information. They questioned whether the low-placed Patronscan signage adequately informs patrons that incident details may be retained longer than the usual 21-day deletion period in Manitoba and shared with other venues. Critics also noted the subjective nature of terms such as 'undesirable' and the potential for disproportionate impacts. Alexandra has filed a complaint with the Office of the Privacy Commissioner of Canada, highlighting broader issues of transparency and data sharing in an era of expanding surveillance technologies.
