The answer to your question is one that we're basically working on right now, and we're working on it together with the Canadian Institute for Health Information, which does this type of work.
The issue for us is privacy and the security of the records. Clearly, if we have these data in these databases, it would be absolutely asinine for us not to be able to do it from a research perspective and a safety perspective. That said, one has to be very careful about Canadians' privacy.
