The LPG is a not-for-profit association of Canadian literary book publishers. Its mandate is to foster the survival, growth and maintenance of Canadian owned and operated publishing houses through advocacy and group initiatives.

Some of the main functions of the LPG are to act as an advocate for its members to the various government and funding bodies; provide members with a sales force that represents them to the Canadian (and in some cases, the US) trade book market; provide access to advertising opportunities through the LPG ad project; and create and implement group sales and marketing initiatives.

LitDistCo, an affiliate of the LPG, provides members of the LPG, as well as other Canadian owned and operated publishing houses, with distribution services.
