the market is open to everyone in Canada.  In order to gain or hold on to their market share, investment needs to be made.  There will be more economic activities.

As I said, having 10 customers and 10 compaines is always better than having 1 customer and 1 company.  More competitions, more investment and more economic activity.

whether or not it is a zero sum game, bigger market always induce  more investment than otherwise.
