This is a great outcome.  Businesses will be able to retain earnings and invest them, for all the good reasons that came out during the consultation, and those who are just using CCPCs as tax shelters, will be limited to much less than they are used to.
The reduction in the small business tax will encourage owners to reinvest in their businesses.  Whatever profits they make and take out as income will be taxed at their personal rate.
The consultation which caused all the uproar was perhaps the first genuine and effective consultation in living memory.  Everyone had a chance to be heard and they were listened to.  The result is a win for Canadian democracy.
