Hi Deanna, you have come to an excellent resource. Folks have already provided great advice.
By posting some decent quality scans of the oldest dated pages for several countries that include larger collections, this community could likely tell you generally if you might own a more in demand collection. That said, most stamps are relatively inexpensive so it's impossible for anyone to guide you sight unseen.
Sound like it is an extensive collection. Possibly with older issued stamps. So there is a good chance you have a somewhat valuable collection. I am unfamiliar with Canadian stamp organizations, but if you go to the American Philatelic Society website
www.stamps.org I'm sure you can find a reputable stamp dealer who can help you determine value. Dealers often take collections on consignment and offer them at auction for a percentage of the sale price. Some dealers may offer a cash buyout price if they see a valuable resale. Best of luck to you!
