Canadian "Police officers can demand that any lawfully-stopped driver provide a preliminary breath sample to test for alcohol without reasonable suspicion that the driver has alcohol in their body."

"Clause 15 (new section 320.27(2)) allows an officer to require a driver to provide a breath sample"

"As research shows that many impaired drivers are able to escape detection at check stops, this authority would help police detect more drivers who are “over 80” and reduce litigation regarding whether or not the officer had a reasonable suspicion."
