The drinking and driving provisions of the Criminal Code were created to protect Canada’s roads and its drivers. Those provisions establish the acceptable blood alcohol content (BAC) levels for Canadian drivers. BAC is the measurement used to determine the quantity of alcohol in your bloodstream. It is expressed in milligrams per 100 milliliters of blood. Currently, the federal legal BAC is 0.08 and driving or being in care and control of a motor vehicle while exceeding this level is a criminal offence.
Essentially all of them mean the same: you were operating a motor vehicle or had a motor vehicle in your care and control while either a) your ability was impaired by alcohol or b) you had a BAC greater than 0.08 at the time the police requested a breathalyzer test.
