New, stricter impaired driving laws are come into effect. 
Police officers will now be able to demand a roadside breath sample from any lawfully stopped driver to determine whether a person has alcohol in their body without first having to suspect the motorist has been drinking.
Bill C-46 initially passed back in June with the first part directed at drug-impaired driving.
Until now, officers had to have a reasonable suspicion that a driver had alcohol in their body before demanding a sample.
Under the new legislation, drivers impaired by alcohol will also face higher mandatory minimum fines and some higher maximum penalties.
