CANSCAIP holds a big conference in Toronto every November as well as regular meetings and events.
There are regional chapters, too. Our Quebec chapter, know as Yes Oui CANSCAIP (Cute name, eh?
) held its first conference last May. It was a huge success and this year's conference will take place on May 28th, in Montreal.http://yesouicanscaip.ca/imagine-a-story-2011/
