Google Maps error directs drivers wrong way on Toronto one-way street
A Google Maps routing error directed drivers to travel northbound on Winona Drive in Toronto, which is a one-way southbound street. The error persisted for several days despite complaints to officials and Google, creating traffic hazards until the company corrected it on Monday.
What happened
Google Maps incorrectly listed Winona Drive in Toronto's Oakwood Village neighbourhood as a northbound-only street when it is actually a one-way street running southbound past Belvidere Avenue. The error was in place as early as April 29.
For several days, the routing error directed drivers to travel the wrong way up the street, creating a flood of vehicles driving northbound. Residents reported the sudden influx of wrong-way drivers and posted homemade signs stating 'GPS is wrong,' but the error persisted.
Reported impact
Residents reported near-misses and safety hazards from the wrong-way traffic, with one resident noting that drivers arrived 'with such gusto' and describing a crossing guard as appearing ready to 'keel over.'
Local councillor Josh Matlow characterized the error as causing 'real and immediate safety impacts on our streets' and called for Google Maps to be more responsive to resident complaints and transparent about its processes.
Index analysis
Google Maps uses AI to understand traffic conditions and predict future traffic patterns, while also analyzing historical traffic data and incorporating authoritative data from local governments and real-time user feedback in its routing decisions.
Governance controls
The City of Toronto's Transportation Services division said it works closely with Google Maps and communicates directly with the company when issues arise, but noted that 'fixes do not happen instantaneously.' By Friday evening, Transportation Services installed temporary 'Do Not Enter' signage at the intersection to prevent wrong-way traffic.
Google stated it takes 'driver safety very seriously' and has rectified the routing error. Councillor Matlow indicated he would follow up with Google Maps to understand what went wrong and what improvements could prevent future occurrences.
