The mission of the Guilde des musiciens et musiciennes du Québec (GMMQ) is to defend and promote the economic, social, moral, and professional interests of its members and musicians in general. Its objective is to negotiate collective agreements with producers and to provide its members with a standard employment contract. This form gives musicians a document containing contractual terms that sets the base fee and other minimum conditions of employment as established by the GMMQ, e.g. the requirement for the producer to pay dues to the musician's pension fund.
Notably, the GMMQ sets minimum working conditions for musicians and acts collectively on behalf of its members when it considers that their interest is affected. To this end, the GMMQ works with organizations whose objectives are similar. It is also actively lobbying to promote music and musicians to local, national, and international government bodies and communities.
In addition, the GMMQ provides musicians with a range of services, such as legal services and preferential rates with several companies, including insurance companies.
