Back when I signed up in Regina, my Dad thought it was a great idea (carrying on the family tradition) to enlist, and he fully supported it, but my Mum was more hestitant, I reckon as most mothers would be. I did need consent as I was underage at the time.
Either way Amber, its your life not your parents, and whatever you choose to do, they should support you. Its not that you are joining some type of twisted brethern, but coming into a career which offers relitively good secuirty, a lengthy term of service, a good pension, and a host of oppertunity for advancement and learning, plus travel overseas and sseing Canada from end to end, which I thnk can only broaden one's horizons. It's not as if you are out there baby burning and war mongering. There are many avenues to choose when joining, and I wish you nothing but good fortune in what ever endeavour you chose.
Your parents should have a more open mind, and encourage and give nothing but positive re-inforcement for their kids (no matter if you are 17, 27 or 45 for that matter, as you'll always be your parents child).
Good luck, and let us know how things go.
Regards,
Wes
