Summary conviction offences, as Ms. Gilmour pointed out, in other legislation have lower caps. The whole point of a summary conviction offence is that it's intended to be for a less significant offence overall. I'm not a prosecutor, nor am I an expert in criminal law. Where that line varies would be an issue for the criminal prosecutor. The point is, if you decide that it's in the lower threshold and appropriate for summary conviction, increasing it to $250,000 gives broader scope for bigger punishment within the lower category.
