I'd be happy to start.
The balance of where the funding comes from depends to a considerable extent on exactly where in the spectrum, from fundamental research to commercialization, we're talking. Clearly the private sector, understandably, is reluctant and generally does not invest in very basic fundamental research. That's true not only in Canada but throughout the world. It is largely the responsibility of government--that is, the public sector--to invest in the very basic fundamental research simply because it is so far upstream that the potentially commercial products simply cannot be predicted. No one could have predicted all of the commercial benefits that would have resulted from Einstein's fundamental research, yet nobody today would deny it. But at the time, no one, including Einstein himself, could have predicted it. So that generally is a role for the public sector, for government.
When we move into technology development, where a considerable amount is done in colleges, there it is a much more balanced funding. We see there that there is public sector funding, but there is also more private sector funding. Once the technology is developed and it's moving into the marketplace, then it becomes predominantly the role of the private sector. The government's role there is largely to facilitate the private sector in terms of fiscal tax policy and other things.
