In the rules, it states that the winner of each group (16 teams) moves up one division.
However, in the division I was in last year (III.1) it looks like they moved at least six teams up to Div II. Now with only 108 teams or so in all of Canada, that's barely enough to fill Div I and II, with a few teams left over. So it sort of makes sense.
But is this intentional to move that many teams, is it a one-time thing they just did last year, or what?
