I would say as a starting point it would be valuable to reach out to the Ministry of Health, which manages the Ontario midwifery program, and to the Ministry of Colleges and Universities in Ontario. Work with them to develop a cohesive plan that looks long term.
At the federal level, it helps to have midwifery recognized even just as a job category because it's not. If the federal government starts with a clear position on midwifery with goals and targets for how they would see midwifery positioned to support birthing people across Canada, that vision can translate down as an expectation to provincial governments for setting their policies and programs.
