[1] The stated purpose of the OLA is to "give profile to the librarians, library workers and trustees in the school, college, university, public and special libraries of Ontario and to foster provincial programs that will improve library services in the institutions and communities our members serve and that will ensure equitable access to information for all citizens of the province.
Three of its most prominent are the Forest of Reading program, the Library Marketplace, and the OLA Super Conference.
[12] The Forest award winners are chosen by votes cast by readers in the target age ranges for each of the specific book categories.
Award winners are announced annually at the Forest of Reading Festival in Toronto.
The Super Conference also includes within it Canada's largest library trade show.
