I think it depends on who you're looking at. If you're looking at the Financial Post 500, you'll see it's around 20-point-something per cent. It will vary across the various sectors.
I think your target range needs to be in the 30% to 40%...and within the next five to 10 years. It can be done very quickly if you start requiring the boards to turn over more quickly, for example, by having board terms for many boards that simply don't have terms at the present time. As I said before, this is leading practice.
I think you need a minimum of 30% as your target, because you will not change the dynamic on a board without at least 30% women. The ideal is somewhere between 40% and 60% in the long run, but you're not going to have a target of 50% or 60% necessarily. You certainly need to go to 30% to 40%.
I would say you need to expedite it because it's been going very slowly despite the business case. The business case is crystal clear. There are so many organizations like McKinsey, Credit Suisse, Goldman Sachs that have pointed out the business case. It's really good business also to add women to your boards.
