I don't think additional safeguards are warranted in the law. I think the system has enough safeguards.
What is needed is more transparency in provincial oversight. We have good data from, say, Ontario, which the coroner, I understand, will make publicly available from the MAID death review team. There need to be networks of accountability mechanisms, which exist already but can be reinforced. That requires investment from the provinces. Ultimately, that's a provincial decision.
These mechanisms are more flexible and appropriate for dealing with complex cases. They're not additional legislative safeguards.
