BCS is known to be an active Canadian Nationalist and prior to being a British Loyalist, where many leaders in the Dominion affairs such as the 7th Speaker of the House of Commons of Canada Sir James David Edgar was raised. Even the Rector of BCS during the Canadian Confederation, the Rev. Henry Hopper Miles (LLD, McGill) was the representative of the Eastern Townships in the London Conference of 1866. The school also collected the first-ever raised Canadian flag in a blessing ceremony a few hours before the Canadian Parliament Hill in 1965. The flag was donated by BCS alumni, a WWII veteran Okill Stuart, who also invited Prince Philip for an inspection visit to BCS. The flag is permanently kept in BCS Chapel, in Québec, where a strong sense of separatism is presented.
