A year ago, I wrote an op-ed in La Presse on this topic.
I'd like to build on my colleague's comments, and say that it would be preferable if transfers were voluntary, but not necessary. We have to be realistic, and see what other countries are doing.
That said, your question is whether this proposal should be included in Bill C‑12. I think it's a policy issue that can be negotiated separately from the bill. The bill already has complex elements. I see no need to add an element that could be politically controversial, as you know.
