Perhaps I can offer a counterpoint to that. Market share and concentration measures are imperfect measures, but when we get into the messy business of enforcing competition law, we need to balance the data we can have and the analysis we can do quickly with the realities of the market. That's the case even with existing competition law. Understanding them as an imperfect indicator, market shares and concentrations still point us frequently in the right direction of where we should be focusing enforcement resources.
The other thing is that the guidelines in Canada don't play the same role as in other jurisdictions. We are much more directive within our own law. I think putting market share statistics in the guidelines would be largely ineffective.
