Sabastian Prosa, 22, testified he had a G2 driver's licence — meaning he was not allowed to have one drop of alcohol in his system if he was driving — when he crashed head-on to a minivan on Highway 427, killing a father and his teen daughter.
"If I drank, I would never drive," Prosa told the court. He faces 12 charges including two counts of impaired driving causing death.
Prosa testified he parked his car at his friend's home in downtown Toronto the day before the August 2012 crash. He said he had four shots of alcohol with friends before heading to a party at a rooftop bar on Front Street.
Prosa said he can't remember where the bar is, how he got there, or going back to his friend's place.
He said he remembers drinking there, but not how much he drank.
Early the following morning, Prosa drove his GMC Envoy the wrong way on Highway 427, crashing into a minivan carrying 49-year-old Neil Wijeratne and his daughter, Eleesha Wijeratne. Both were killed.
Neil Wijeratne's wife, Antonette, was also seriously injured in the crash.
When asked by an arresting officer if he'd taken drugs or alcohol, Prosa answered "I drank a lot," according to an agreed-upon statement of facts.
When asked how much, Prosa repeated, "A lot."
A blood test found he had about twice the legal limit of alcohol in his system.
Prosa suggested in court on Wednesday someone might have "put something" in his drink.
When asked by his lawyer if he'd ever drank so much he blacked out or lost consciousness, Prosa said he had not.
He testified he didn't intend to drive that night.
Prosa's lawyer, Alan Gold, wants all of the charges dropped because the blood sample was lost and cannot be independently tested.
