Hey Allan! Welcome aboard from a fellow Canuck. There are a bunch of us active in the GTA. I'm in Waterdown and finished my AP build in February of this year.
As mentioned, start your build thread. Set up an IMGUR account, post lots of pictures and ask lots of questions. Since you're aiming for Centurion a little detail and research can go a LONG way.
Make use of all the great resources and the community on this board. Here are a few quick links: https://www.whitearmor.net/forum/topic/42381-howto-post-images-in-threads-using-imgur-easy/ https://www.whitearmor.net/forum/topic/31404-supply-list-for-your-tk-build/
Feel free to PM me at any time as well.
