G. A. Chambers was a charter member and First General Superintendent of The Pentecostal Assemblies of Canada- a post he held from 1919-1934. In 1901, Chambers attended God's Bible School in Cincinnati, a radical Methodist school led by Martin Wells Knapp. While attending the school, he joined fellow students A. G. Ward and R. E. McAlister - men who would play major roles in the birth of the Canadian Pentecostal movement. Chambers returned to Ontario and was ordained in the Mennonite Brethren In Christ and pastored in Guelph, Ontario and later in Toronto. While in Toronto, he heard about the outpouring of the Holy Spirit at the East End Mission led by Ellen Hebden. He first rejected the work, but later became attracted to the Pentecostal experience and invited Methodist circuit preacher A. G. Ward to speak at his MBIC Church in Toronto. Chambers subsequently began to preach on the baptism in the Holy Spirit with the evidence of speaking in tongues. As a result, the MBIC suspended Chambers from ministry. At the 1908 MBIC Conference at Bethany Church in Kitchener, the conference officially voted to reject 'the tongues movement'. Consequently, Chambers and over 100 other MBIC ministers and lay people left to form the nucleus of the Pentecostal movement in Ontario.Chambers then founded a Pentecostal Mission at 375 Parliament Street in Toronto and joined with five other Pentecostal Missions to form the United Pentecostal Missions of Toronto (Ellen Hebden, Stephen Craig, George Murray, John Salmon, and George Fisher). In 1909, the six missions gathered for a Pentecostal Camp Meeting at Dickson's Hill in Markham hosted by Chamber's friend A. G. Ward. Chambers later pastored a Pentecostal Church in Elkland, Pennsylvania, and then located to Vineland, Ontario where he hosted a Pentecostal Camp Meeting at Hayne's Bush in Jordan Station. In 1917, Chambers and other Pentecostal leaders met at Fred Young's home in Mille Roche, Ontario to form The Pentecostal Assemblies of Canada- which officially gained charter status in May 1919. At the first PAOC National Conference in 1919 (located in Kitchener - just a short walk from the Bethany MBIC church), Chambers was elected as Chairman. He served in this capacity for 15 years, travelling the nation, raising up leaders, and organizing a national fellowship with great effectiveness. Chambers served the PAOC as a national leader, conference speaker, writer, evangelist, radio broadcaster, and spiritual father to hundreds of young leaders across Canada. With a deep spirituality and great zeal for righteousness, Chambers made a tremendous contribution to the Pentecostal movement throughout Canada. The Sunday before he passed away, he was preaching at Kitchener Gospel Temple. A few days later, he died of a heart attack.
