Welcome to Army.ca, Fancy Boots
From the "READ FIRST" http://army.ca/forums/threads/115341.0.html stickied thread on this Forum, which I am sure that you read first: "This section is for persons who have questions about joining the Canadian Armed Forces, occupations, different enrolment programs, and prerequisites. Much of the information can be found at Forces.ca, or the Recruiting FAQ and wiki section of this site. Before you ask a question, you should be searching the forum or the Forces.ca website for these answers."
There is information regarding this - and a ton of other things - elsewhere on the Site. The process is "Excused Drill and Training", or "ED&T".
Please explore the Site and read through some of the older threads. In doing so, you will likely find answers to other questions before you even think of them.
I will move this thread to an open forum later. Others can then be of more assistance, if you truly cannot find an answer.
