It all depends on a lot of things.. For the moment my guess would be that, provided there are no issues with your medical and background checks, you would be merit listed after selections for the new fiscal year in April (since most for 2015 would be given out already). If you scored well enough on your CFAT and there arent any issues with your application, you may get lucky and be enrolled for BMOQ for the summer... if you are selected. In 2015 I believe a course ran in Jan/Feb, then in June, Aug, Oct. You can always check the CFLRS webite to see when the last courses were offered as well.
My comments/opinions are based solely on my experience in the recruiting process - Im not a recruiter or have any privvy information.. but I went through the same thought process and certainly know how exciting it is! Good luck!
