I'm not sure that at the time there was even the idea of corporate sponsorship. The business community was actively involved. The Royal Bank of Canada had a number of initiatives, and I think it supported some publications. Similarly, I believe E. B. Eddy used to have a presence on the river here; I think they were matchstick makers. They also had a presence and contributed. The contribution was by way of some of their own initiatives to promote and celebrate the centennial.
So I can't speak confidently to the theme of corporate sponsorship or partnering. It was more that they were in alignment and supportive of the federal framework, and looking for ways to promote and lever the centennial.
