The Canadian Participatory Committee for UNCED organized a meeting between government and other stakeholders on October 23, 1992 at which NGOs were able to respond to the Canadian Government's draft position for the General Assembly discussions on the CSD. A National Stakeholder Meeting was held in Ottawa on 5-6 November 1992, where representatives from every major sector of Canadian society, including business associations, community organizations and indigenous peoples agreed to accept Minister Jean Charest's challenge for a "projet de société".

The Canadian Council of Ministers of the Environment, the major intergovernmental forum in Canada for discussion and joint action on environmental issues of national and international concern, pursued a three-point action plan as follow-up to UNCED. The three points included: early ratification and implementation of the Climate Change and Biodiversity Conventions; action on Agenda 21; and integration of the environment and economy in decision making. Once both conventions were ratified, efforts were concentrated on seven priority areas of Agenda 21: human settlements; freshwater; toxic chemicals; hazardous waste; indigenous peoples; human health and foreign overfishing on Canada's east coast. In the short term, a framework document for harmonization and integration of the different sustainable development strategies across the country is being developed. A special Follow-Up Task Group was established to plan for and pursue the follow-up to the Rio conference.
