I can’t find an actual published sentencing decision, best I could find was a news story from the time:
From the facts laid out in there I’m actually surprised crown kept pushing a criminal charge at all versus a provincial careless driving charge. Criminal dangerous operation’s a pretty high threshold, and he would be able to argue that the car behind him was able to safely stop, and that the other driver who ate the fail to stop charge was much a part of the problem and only got a provincial ticket… So it was a chancy prosecution. In terms of the specific sentence, it would have been mitigated by his plea, and by shared responsibility for the crash. I suspect crown probably agreed to a good deal to secure the very uncertain criminal conviction. Crown may also have been skittish about going to court with how very delayed that prosecution was- 2018 to mid 2023. Defence could probably have made an potentially won a Jordan stay.
So yeah it’s a very unsatisfying sentence but I can see how it happened.
