re: OSK exercise 8B Postal Codes

It appears that PO Box 22 no longer exists in Edmonton - neither does PO Box 220, for that matter. Don't stress about Jeff Bacon. The other addresses all seem to still be current. The forms were updated in 2010 and unfortunately I don't have authority to redo them. If you can find a potential address, include it and let me know how you came to your conclusion!
