The Cathedral of St. Alban the Martyr is an Anglican church in Toronto, Ontario, which serves as the school chapel of Royal St. George's College. Completed in 1891, what stands today is only two-thirds of the planned Gothic Revival church designed by Richard C. Windeyer, Sr. to serve as the cathedral of the Anglican Diocese of Toronto. Though only the chancel was completed, the church still held cathedral status from its construction until 1936 and is still referred to as such today.
