The short answer is money.
The long answer is this. When I was in government, I was minister for international trade with added responsibility for the Asia-Pacific gateways and corridors initiative. In our report we have noted that other countries in the world looked at what we did there, which was to integrate transportation trade-related corridors, and infrastructure decision-making was driven by the merits of the investment for the trade corridor. It wasn't building ice rinks in politically marginal ridings or anything.
