I think there's a philosophical element there. To what extent should governments be responsible for marketing companies' products? When you're talking about a budget, you're talking about the government budget. I suspect that Canadian enterprises selling into the United States are spending considerably more than that promoting their goods and services in that market. I think for the most part, if a company wants to sell something, it's the company's responsibility to do the selling.
That said, I don't think as a country we're successful enough in expanding our base of exporters. The notion of government assistance is more important for companies that are trying to grow and break into new markets, whether in the United States or elsewhere.
