The federal government isn’t looking at using location data from Canadians’ phones to track cases of the novel coronavirus, but isn’t ruling it out in the future, Prime Minister Justin Trudeau said Tuesday.

“I think we recognize that in an emergency situation we need to take certain steps that wouldn’t be taken in a non-emergency situation, but as far as I know that is not a situation we are looking at right now,” he said.

Trudeau’s comments follow confusing messages from the city of Toronto about whether officials there were using location data from residents’ phones.

“We had … the cellphone companies give us all the data on the pinging off their network on the weekend so we could see, ‘Where were people still congregating?’” quoted Tory as saying Monday evening.

Tory described the measures as “something we’re doing now … I asked for it, and I’m getting it.”

“The City of Toronto will not be using cell phone location data, nor does it have such data, to determine where people are not practicing physical distancing.

He did not respond to requests for clarification.

Mayoral spokesperson Don Peat told Global News that Tory was answering a question about ways technology could “possibly” help fight COVID-19.

“As City staff made clear this morning, the City of Toronto is not collecting cell phone location data, nor has it received any such data,” he said.
