Transport Canada has issued a warning to drivers in Calgary, saying the service has stopped operating due to the city’s “unreliable” system for tracking passengers.

The city has been in a collision-course with Uber, which is under investigation by Transport Canada for failing to pay drivers on time.

The Calgary Police Service says it has a system in place that allows police to pull over and verify that a driver has complied with their conditions of licence.

“The Calgary Police Services and the Transportation Safety Board have agreed to work together to develop a robust, reliable, and transparent transit and road safety tracking system that ensures safety and security for all travellers,” said spokesman Jason Doucette in a statement.

The province said it will share the information, including the number of times a vehicle was pulled over and how long it took to be pulled over, with Uber to ensure the service is “reliable and efficient.”

“The system will also provide real-time, real-data information that will enable the Calgary Police to provide better services for passengers, including identifying where the most serious offences are occurring and identifying areas of concern,” the statement said.

It was not immediately clear if the city would require Uber to provide the information.
