s. 254 Breath Demand: Who is a peace officer?

The accused, a Canadian citizen, was driving back into Canada from the U.S. at the Windsor border crossing. He was dealt with by a border service officer (BSO) who noticed that the accused's speech was slurred, his eyes were "a little glossy and red", and there was a "small, faint" smell of alcohol on his breath. The BSO asked the appellant if he had been drinking and the accused responded that he had consumed three drinks. The BSO requested that the accused turn his car off and hand over the keys and then called for a second BSO who was designated under the Customs Act as having powers under specific sections of the Criminal Code to respond to suspected impaired drivers. Two designated BSOs arrived and directed the accused to get out of the car. The accused stumbled as he left the car, had bloodshot eyes, smelled of alcohol, and spoke in a "loud and cocky" manner. Based on these observations a designated BSO formed the opinion that the accused's ability to drive was impaired and arrested him for impaired driving. A constable from the Windsor Police Service attended the customs detention area to take the appellant to the police station. At trial the accused was convicted of impaired driving and that conviction was upheld at the first appeal.
