I think it probably won't make a lot of difference, because it's relatively trivial. My experience of the tax credit has been that you're always unsure about whether you have the tax credit or not, so you operate as though you don't, and when it comes, it's a windfall. So it isn't a stimulus.
In the case of the direct funding—I've been on the board of IRAP—industry does about $15 billion worth of R and D, which is low for a country like Canada, and IRAP had about $80 million. Even doubling that really doesn't get us into the mode.
