That answer has two parts. The first part is that with any law that has this type of complexity, I'd expect it to evolve, so although you are obliged to create a law that is thoughtfully put together, there should be thought on how it will grow over the years. Dr. Grant commented that what is a grievous and irremediable condition that is incurable today may not be that tomorrow. There needs to be room for growth in that way.
The second part is that consultation needs to happen over a period of time, and as you rightly state, the three or four months that you currently have, no matter how you do it, won't be adequate for consultation. That time won't allow people to reflect on the magnitude and weight of what is happening.
How do you do that in a measured way? I think you already have a network of indigenous organizations that could weigh in, so first reach out to them and ask them to put together a position paper on it that discusses some of the issues that I brought up, and they will have others that they will bring up.
Ensure that there is a transparent oversight process specifically for indigenous people, which includes jurisdictional ambiguities that often exist through federally administered programs. Most important to me in my experience with indigenous patients is to ensure that there is a feedback mechanism to hear from patients, so once the law ends up being passed, that there is a component of the law that allows patients to report back to some type of centralized body. Whether you invest that responsibility within the regulatory colleges in provinces or wherever, ensure that you actually assign someone to deal with complaints about the process. As the law evolves, that consultation will be an important part of how that law ends up growing and changing.
