I am so excited; I found a supplier of cake decorating supplies in Pickering, Ontario . They also run classes with high profile guest instructors such as James Rosselle. Check it out if you're interested:

I recently ordered cake stencils from them and can't wait to try them out.

I have also ordered numerous times from Golda's Kitchen in Mississauga, Ontario - they are awesome! Excellent customer service and very quick delivery:
