The Ontario Library Consortium (OLC) consists of 27 library systems: 11 county and regional municipality and 16 medium-sized public libraries located in southern Ontario. It includes over 180 branch libraries and 27 headquarters, serving approximately 8% of the Ontario population.

The OLC continues to develop library processes together, through joint custom programming, negotiations of bulk rates with vendors, and co-operative training and support. Priorities, activities and membership costs of the OLC are determined by the members:

1. To provide library users in Ontario with an integrated network of library services.

2. To ensure that library users in Ontario achieve maximum benefit from advanced technology by means of cooperative use of resources.

3. To ensure that member libraries achieve maximum benefits at a lower cost and by increased efficiency through cooperative purchase of equipment, services and materials.
