western part of the Diocese of’ Kingston. As an Episcopal see, it extended
from the shores of Lake Ontario north to Georgian Bay and from the shores of
Lake Superior to the border of the Archdiocese of St. Boniface, Manitoba. The
diocese had a Catholic population of about 30,000 and Bishop Jean Francois Jamot,
the first Bishop, took residence here.
