Trudeau said the app, which will be tested in Ontario, will notify users if they’ve been exposed to COVID-19 and its use will be “completely voluntary” — but he argued the digital tool will be “most effective” if as many people as possible download and use it.
“At no time will personal information be collected and shared, and no location services will be used,” the prime minister said. “The privacy of Canadians will be fully respected.”
Trudeau’s update came as Canada’s COVID-19 count surpassed 100,000 known cases and about four weeks after he said the federal government was reviewing several smartphone apps and gearing up to “recommend strongly” a particular app.
Contact tracing is considered crucial to limiting the spread of the coronavirus. During the COVID-19 pandemic, public health authorities have had dedicated people call individuals who tested positive for the virus and track down any close contacts of theirs in the two weeks prior.
Having one app available across the country will provide a “layer of additional effort” to manual contact tracing, Trudeau said on Thursday. He said there are more than 30 million smartphones in Canada that are compatible with the app.
However, the federal, provincial and territorial privacy commissioners — as well as other privacy experts — have warned that using a digital app as public health tool could have “significant implications” for Canadians’ privacy. The commissioners also called for voluntary use of the apps to build “public trust.”
Trudeau confirmed use of the nationwide app will be voluntary and said it “functions entirely on an anonymized basis.”
Each user will have a randomized code associated with their phone, he said. If a user tests positive for the virus, a health-care professional will help them upload their test status anonymously to a national network.
Other app users whose devices have been in proximity to the phone belonging to the person with the coronavirus will then be alerted that they’ve been exposed to someone with COVID-19. That notification will encourage those other people to reach out to their local public health authorities, according to Trudeau.
The Canadian Digital Service will control the “secure” national database that will hold all the randomized codes, the prime minister said.
Canada’s privacy commissioner “has been worked with” on the app, which Trudeau described as “super simple and “super secure.”
“It’s something that you can just download and forget about,” he said. “This is an approach that we are confident is going to make a big difference.”
The province of Alberta already launched and is using its own app, called ABTraceTogether.
