If they live on base, every evening and weekend, just like in civvie life. Except for when you‘re on Ex obviously you can‘t bring your family out to the field with you =)
But just as a warning, when you‘re undergoing your initial training(Basic and then your Trade training) you can‘t expect to have them with you until you get posted to your unit. I know some guys who are on my course right now that haven‘t lived with their families in almost 6 months. That doesn‘t mean they haven‘t seen them, it just means they have had to live in the shacks with us single guys on course for that time.
In most cases, life in the CF is almost like working at a civvie job.
You‘ll have plenty of time to be with your family, don‘t worry.
