I think what most people mean by “patronage” is that unqualified people who are undeserving obtain appointments because of some political favouritism. I think that's what most people think patronage is.
That's certainly not applicable here. These were highly qualified people who were heavily engaged in their practices and who were prepared to take some intense time to help prepare the largest Canadian budget in history. It has nothing to do with what you suggest. It has to do with qualified people doing a good job for the government and value for money for the people of Canada.
