"Canadian Power and Sail Squadrons / Escadrille canadiennes de plaisance (CPS-ECP) is an organization of recreational boaters with over 20,000 active members. CPS is headquartered in Toronto, Ontario. Its volunteer instructors help recreational boaters improve their boating safety knowledge as well as their vessel handling and navigation skills. CPS offers boating safety courses every year and provides qualification for the Pleasure Craft Operator Card (PCOC). Its patron is HRH Prince Philip, Duke of Edinburgh. Canadian Power Squadrons was founded in Windsor, Ontario in 1938 after a group of boaters travelled to the Detroit Power Squadron to take the United States Power Squadrons Coastal Navigation Course. Upon their successful completion of the course, they formed the Windsor Power Squadron, closely followed by the formation of Squadrons in Sarnia, London and Toronto. CPS now has 166 Squadrons in all provinces and the Yukon Territory."

The Power Squadron concept was originated by sailors returning from the First World War, where they had learned the importance of formal training. They wanted to pass along their good seamanship skills and knowledge to fellow boaters. Over time, CPS-ECP courses incorporated sailing too, and the name of the national organization changed to reflect the educational needs of the whole community of Canadian recreational boaters, power and sail. 

Blue Heron Power & Sail Squadron was chartered in 1961

PEI's first Squadron was established by the Canadian Power Squadrons, as it was then known, on an application from 15 Island CPS members. The Warrant was signed by Donald E. Wood (S), national Secretary. Alex R. Neville G.P., Chief Commander.

The original charter was cared for by Henry Scales until 2004, when it went on display at the Charlottetown Yacht Club. The charter reads, "Canadian Power Squadrons. Squadron Warrant. Be it known that upon application made pursuant to resolution of the Governing Board of Canadian Power Squadrons, a Squadron has been constituted, known as Charlottetown Power Squadron."

We confirmed with CPS-ECP headquarters that the official start date of the Squadron was 02 June 1961. In 2009, National staff found in old minutes that Charlottetown Squadron's Regulations were approved on June 2, 1961. This is the only official record we can find regarding the start of the Squadron. The Squadron's number is 05-01: 05 for Atlantic District, and 01 for the first Squadron in the District.
