Although actions to reduce social inequalities in health cannot be considered the exclusive responsibility of public health actors, they should at least make sure their interventions account for these inequalities. However, the actors involved in these interventions have few tools to support them in this process. Therefore, building on a study conducted in France, we have adapted, tested, and developed in Quebec a tool intended to help actors take into account social inequalities in health. The article presents the approach that led to the adaptation of the tool to the Quebec context, to describe the tool, and then to discuss some issues for inclusion in professional practices. A participatory and constructive process between researchers, managers and practitioners led to a useful and useable tool. It is composed of five aspects of intervention (planning, implementation, evaluation, sustainability, and empowerment) and 44 items for discussion presented as questions. A user guide, a glossary, and some practical examples accompany the tool. It follows a reflexive and constructive process wherein a third party facilitator can assist actors involved in an intervention to analyze how they take social inequalities in health into account. This assessment can help generate collective recommendations for improvements, which can be monitored over time, to improve consideration of equity in public health interventions. The article concludes on some issues related to its integration into professional practices.
