Alumni from across Canada are gathering at St. Peter’s Seminary in London this week for centennial and homecoming celebrations. St. Peter’s is one of three major Roman Catholic English speaking seminaries in Canada located on the banks of the Thames next to Western University. “It’s wonderful to be celebrating 100 years of formation at 1041 Waterloo St. and we are looking forward to another 100 years,” said Rev. Peter Keller.

More than 1,000 priests have graduated from the institution, including deacons, bishops and a cardinal.
