In a continued effort by the CSSHL and its member programs for a competitive, like-on-like game schedule, the new U17 Prep division will see 33 teams compete in one division. All 33 teams will participate in 3 division wide ranked showcases, for a total of 12 games, plus additional regional games.
- October 6-9 – Calgary, AB
- January 11-14 – Vancouver, BC and Area
- February 2-5 – Winnipeg, MB
- Teams are broken up into tiers depending on the number of teams in each division
- Flex games do not have any impact on the showcase rankings
- Regional showcases are run separate from full division showcases, and these regional showcases have their own rankings based specifically off regional showcase results
- Teams only play other teams within their bracket at these showcase events
- First showcase for 2023-24 will be based on the 2022-23 regular season results
- At the conclusion of each showcase the teams are re-seeded for the next showcase
- The worst two records in brackets 1 and 2 each move down a single bracket. The best two records in brackets 2 and 3 move up a single bracket
The current rankings for the U17 Division are as follows:
Bracket 1: Teams 1-12
Bracket 2: Teams 13-24
Bracket 3: Teams 25-36
