No. But there are already rules in the Criminal Code that deal with that situation. There is a combination of effect between the Corrections and Conditional Release Act and the Criminal Code, which would require that the second period of parole ineligibility be added to what is left of the first. In other words, the clock would start running again.
So if somebody commits one murder prior to this legislation coming into force—and I presume, from your example, that they've been captured, convicted, and are serving a prison sentence—and commit another one, if they've served 10 years of that first parole ineligibility period, say, the law automatically adds another 25. So they would serve 35 years. That happens automatically right now.
