I applied early May 05 and my file wasn't approved until 2 days after the cut off date, long story short I couldn't go to basic and had to wait till the following summer, but it was well worth the wait. The cut off date was about a week or 2 before the bmq course date. The best bet is to apply asap, now since your b-day isn't till mid April that wont work for you. First, if you havn't ran the decision by your folks do it now as you will need their consent to join the reserves. You will need a transcript from your highschool and 2 letters of references, as well as other paper work. Contact your recruiting centre and pick up all the forms necessary and have them completed before your birthday so when you turn 16 you're ready to hand them and don't have to waste a few day or more getting all your paper work ready. Hope that helps; good luck!
