Wood Island(s) Postal Service 1855 – 1980. When Prince Edward Island joined Canada (in 1873), its postal administration was absorbed into the federal Post Office Department, until transferred to Canada Post Corporation (in 1981). Long before rural mail delivery began, mail was to be picked up or left at the post office, with facilities generally supplied by the postmaster. Typically (Type 11 Revenue Offices) operating from the general store or in the home of a community resident, Wood Island(s) was served by five Post Offices. Wood Islands first 'Colonial' Post Office seems to have opened in Wood Island (North) in 1855, until confirmed as a 'Canadian' Post Office in 1874. Postal services were fully available 'directly' in Wood Islands until the closing of its 'Summer' Post Office in June 1980.
