There's no necessary relationship between P3s being located in Canada and the investors being in Canada. Certainly the CPPIB, the Canada Pension Plan Investment Board, is one of the big investors in P3s in Canada, but P3s are just as likely to be located in tax havens, for instance. One of the interesting new trends that the infrastructure bank may well accelerate is the tranching of P3s, such that it's not one company or one consortium that's responsible for the financing of P3s after about five years. Instead, the P3 is sliced up into 10 or 20 pieces that are sold off individually, such that a single P3 could have 10, 20, 30 owners, with investment funds from around the world, and such that those profits are not returning to Canada by any stretch of the imagination.
