Here are some Canadian specific numismatic books or newspapers available for purchase in book stores and coin stores.
The "Standard". From the Charlton Press, this has a wealth of information and up to date price guides. Canadian Coins 61st Edition
A very good reference for pricing and listings of may varieties not included in other catalogs. Very few pictures and no help identifying varieties, this is still a good purchase for the serious collector. The Canadian Currency Collection. By Brookstone Publishing.
Another very good reference for the variety collector is the book of Canadian coins and Their Varieties by Pierre Charest. Lots of pictures and up to date pricing.
Published every two weeks, The Canadian Coin News has pricing for coins as well as news storys and reports from auctions.
