I haven't given that much thought this morning, but since you are raising the question, I will comment.
Over the past few years, I have often been invited to appear before a committee where discussions frequently concerned a much broader bill. I didn't know amendments could not be proposed. I personally have no amendment to put forward. I think that the proposed amendments are related to the 10-year-old review of the BDC, at the organization's request.
Generally speaking, I don't see why the committee could not issue recommendations.
