It is not seen as directly advantageous to a specific company to participate in a national or a Canadian securities commission as much as it is seen to be to the advantage of the system as a whole to have a Canadian securities commission. The opt-in identified by the panel as a possible future option is to allow companies to take advantage of the efficiency and overall effectiveness of a national, or a pan-Canadian, securities commission. As far as I am aware, there is no particular financial advantage for a company to do so.
