I can't speak to the five years prior to our government. Under the Harper Conservatives, the agencies experienced significant cuts. However, I can tell you that during the five years we were in government we increased funding to the Public Health Agency of Canada. In 2014-15, the funding was $637 million. We increased that funding by 6% in 2018-19, when the funding was $675.4 million.
I say this because that's the nature of how these conversations happen at cabinet. It is rare that a minister would come forward with a specific request about a specific line item. Rather, they would submit those budget proposals to the finance minister and work directly with the finance minister, unless it was changing a program in its specific nature.
