Do your research before you decide on a trade that will suit your skillset and lifestyle. Some trades have specific educational requirements such as the completion of Grade 11 or 12 High School Math, English and/or Science. For the province of Quebec, a professional education diploma P.E.D. is mandatory.
Note: Have you decided where you plan to live and when you are ready to begin your new career? It is important to have a plan as to where you wish to live after your military service, and the conditions of work you want (travel, stay at home overtime).
Your release: Matching a release date with a start of training can vary from one province to another and from one trade to another. Be aware that some trades might only have 1 or 2 intake dates per year and these intake dates might not always match with your planned release date. Also, if you are on a 3a or 3b release and entitled to vocational rehabilitation, take advantage of this time to complete any prerequisites you might require for the selected trade.
