I'm from Toronto as well. Welcome! I started with the Al stohlman books from Tandy. Watched some of their basic videos, Nigel and Ian as have been mentioned and just started working at it. When a new project presented something new I went and found books to DVD and YouTube sources... Sheridan carving etc. As an example.
I get leather from Tandy (Markham shop which uses to be Scarboro and real close to me) if necessary but usually through a friend with a serious leather goods production product shop in Guelph. I am eating for a chance to try an order with some new guys out west who just started up and seem to have good prices and free shipping in Canada... name escapes me and it isn't on my phone here. I will find the name and post them.
And search this forum as creatively as you can... if you are going to ask it... chances are it already has been in some form or another and answered here by those who have gone on ahead of us in the craft... even if only by a day!
I am in the east end if you ever want to meet for a coffee and leather chat.
