This would be very broadly interpreted. Be creative, if you can find a Canadian angle in the book, I'll accept it. A Canadian setting, a Canadian main character, a Canadian illustrator, etc. If you are posting a list of items for sale, and you are not quoting in Canadian funds, you should specifically state this. It will be assumed that any posting without reference to currency is in Canadian dollars.
Any Canadian member is welcome to post catalogue or list announcements in any subject category.
Something like - I have a new list of WWII Military titles available. Non-Canadian members may post FS postings for Canadian materials. They also may post catalogue or list announcements if there is substantial Canadian content. There is no limitation on the content of WTB postings by Canadians. Non-Canadian members are welcome to post WTB postings for Canadian materials.
