There is no formal BCPL programming between the evaluations (starting now) and the start of the mini-season in the fall. However, (a) players are free to register with a spring/summer team such as SYL or academies (indeed, CMF is having their incoming U13s play in U12 SYL); (b) players may have been selected to the PTP or to Whitecaps teams; (c) PL teams may choose to begin training); (d) players are free to take some time off and recharge their batteries.
Once the mini-season ends (in November actually), the HPL Committee periodization plan calls for a mandatory break between the end of one season and the start of next and between competition phases 1 and 2 so no, kids that are enthused etc will not necessarily continue training. If a player does not wish to continue with the BCPL, they would have the option of playing in a lower-tiered league. Under that scenario, it is reasonable to assume that for each player dropping out of the BCPL, a lower-tiered player will be taking his/her place. Assuming Rule 23 isn't involved (it will be in some cases), the MSL-exiting player will leave a gap which the BCPL-exiting player could presumably fill (and vice versa). There will not be 100% correlation of course but it should keep the logistical issues to a minimum. Tier 2 and BCPL clubs and teams will have to be in synch with regards to this player movement (but then there should be on-going communication anyway to keep the player identification process rolling along). As to the timing, MSL leagues typically go quiet for 4 weeks or so over Christmas and then start up in the new year at about the same time that BCPL tryouts commence. The exiting BCPL player may miss some weeks of soccer yes but it is not an inordinate amount of time.
It is unlikely that a player will be permitted to complete their MSL season and then, prior to cup play, join a BCPL team. For starters, the evaluations for BCPL happen in Jan-Feb. Pre-Season starts the 2nd week of Feb and the regular season begins March 1. A player would have move up to the BCPL long before April. In addition, playing for such a period of time goes against the spirit/policy of the mandatory transition periods. There are going to have to be rules in place about the movement from one league to another to avoid players from playing 12 months of the year (which the periodization plan was designed to prevent) but, like everything else in this post, such issues, while being discussed now, are not finalized.
