Here is the section of the 1959 Canada Official Postal Guide which deals with refused or undeliverable second class mail:

Does anyone have any information on where I may purchase one?
1. Check
ebay and Delcampe often. It is amazing what pops up.
2. Go to stamp bourses and look through as many cover boxes as you can.
3. Contact the British North American Philatelic Society and find out who collects this sort of thing.
4. Be patient. It may take years for you to find a wrapper at a reasonable price.
