The Canadian boreal forest is primarily public land, owned and managed by provincial governments on behalf of the public interest. Boreal forest governance consists of a complex patchwork of federal and provincial legislation, policies, tenures, and delegated authorities designed to achieve multiple (and often conflicting) social, ecological, and economic objectives. We examine the implications of boreal governance arrangements for sustainable management of ecosystem services. The paper shows how current multi-level governance arrangements that evolved from Canada’s Constitution Act are not effective at managing the cross-scale and cross-sectoral challenges of ecosystem services and have created a crisis of legitimacy for forest decisions. We show how the rise of nonstate arrangements, marketization, and decentralization are partly a response to governance gaps for ecosystem services as well as a reflection of global trends in forest governance. Past trends related to governance themes (the role and scope of government, the level of integration and coordination, Indigenous empowerment, and geopolitical influences) are used to motivate future governance scenarios.
