Keep in mind the CAF is going to eventually expect your spouse to move with you. During training, depending on trade and course length you'll likely be not able to move your family to you. Your husband should take that time to get ready to move on completion of your course. If you start your career by wanting an IR move, it will reflect well. You may also request your first posting to where your husband is (if there is a base with positions there), provided its reasonable that a brand new person in the trade would go there. To secure better chances of that request being granted, be at, or near the top of your course.
If you find a few years into your career that you have too many conflicting priorities between yours and your husband's work, you'll need to sit down and make some hard choices. The RegF lifestyle is not for all family situations, and you may be able to consider the Reserves or changing trades (if you're able) that might match your situation better. Never expect to be able to stay at a base for 15 years because your husband has a good job.
