New to all of this!

Hi there! I'm in Canada (Ontario) and my family and I have been contemplating fostering for sometime now. In recent months I called the Children's Aid Society in our area who facilitates the program (like CPS for my american friends) in an effort to obtain some information - ins and outs... process... etc... all I was told was: "I will send you a application which you can fillout and then we would schedule a home visit" I was taken aback by the lack of enthusiasim and effort in aquiring a foster family with the need to place children being so high... but be that as it may, I ended up doing all the talking and asking all the questions - i chalked it up to maybe she had a bad day? Tired of talking to hopefuls that never came through? I called a family meeting and sat my stepkids (12 & 14) down with their dad and myself to talk to the kids about our plans. This went extremely well, but I really had not much to share with them aside from "our plans" to foster, explaining that it would become a commitment and life adjustment for us all and that we may have a new member of the family for a short while or a long while. We would have to wait and see. Unfortunately, for as much as I want to jump into this all right now, I can't. I promised the kids this year we would have a family vacation just the four of us as we usually tend to take someone along with us every year on vacation. So in August we are doing a cruise followed by 8 days at the house of the mouse in Florida after which we plan on having a final sit down with the kids and start paperwork. I love children, but I have to be honest... and maybe I am being a bit unreasonable... but I could not care for a teen (My kids are young teens and they are good kids and I really an discouraged by the thought of introducing a troubled teen into my home - and I do understand that not all teens are troubled). I have no preference for sex or race, but can I stipulate any preferences on age? Health conditions, illness, disabilities or handicaps? I do not take any preference for any religion, but I do not practice my own, and would prefer not to practice any... I just have so many questions... and the SW was less then helpful until she does a home visit by the sounds of it. Any experience you share is helpful. Thanks.
