Canada is actually super good about this. If you're coming from Australia, the official immigration docs ask do you have a DUI? If yes, was it below .07 Blood Alcohol Content? (In Australia the crime is .05 or above, but in Canada the crime is only > .07) So even if you broke the law in Australia and got a DUI at .06, Canada will ignore it, because technically driving at .06 in Canada is not a crime, so they don't deem you to have committed a crime at all!
