The diocese comprises over 126,000 square kilometres of the civil Province of Alberta, consisting of a band across the central part of the province, extending to the borders of the adjacent provinces of British Columbia to the west and Saskatchewan to the east.

Its See city is Edmonton, and its roughly 7,000 Anglicans on parish rolls are served by 53 parishes, according to the most recent figures published by the Anglican Church of Canada.

The following year, the diocese was incorporated by the Alberta legislature.

A lay order, the Company of the Cross ran the Saint John's School of Alberta which closed in 2008.

In the past, the school and order were specifically under the control of the diocese and bishop.
