I would hope it wouldn't happen again.
I don't know the cases you're talking about. I assume it's something that happened after the Supreme Court decision in Askov, when cases across the country were thrown out because of delay.
We try to ensure that our cases are handled promptly and don't run afoul of Askov. This doesn't mean that even today, at the provincial level, cases don't occasionally get dismissed, or stayed, because of prosecutor delay; and it doesn't mean it might not happen with us. But I would hope it wouldn't happen, as you say, for a large volume of cases.
