I think one of the successes of the bill that was passed in June is that now anyone who has an indictable offence, or an offence that the court can't confirm was summary, has to write a personal explanation letter on why they feel they deserve a pardon. With that they can conclude any paperwork showing any rehabilitation.
So it's not a matter of three, four, or five strikes and you're out; it's based on the person, their character, where they are at that point of their life, why they feel they deserve a pardon, and evidence of rehabilitation. It's no longer a rubber stamp, but it gives people the opportunity to show they have changed.
