The cost question is something that the department has not looked into. There are so many other questions that would need to be clarified before looking into the cost. First, which federal institution would be well placed to implement a registry? What type of registry would it be? Would it be for research or traceability purposes? Then there's the involvement of the provincial and territorial health authorities, etc.
I think, with all these considerations at this time, it's not possible to have information on the cost. What we know, though, is that it would be quite expensive.
Perhaps my colleague from CIHI could provide more information on the costs related to the only registry we have for medical devices.
