In 2000, David Johnston's first full year as President of the University of Waterloo, he received $281,820.22 in salary and benefits. 

Johnston's predecessor, James Downey, received $212,210.07 for doing the same job in 1998.

In 2010, the year Johnston was appointed Governor General, he received $1,056,813.56 in salary and benefits from the University of Waterloo.

In 2011, the year after Johnston was appointed Governor General, he received another $610,506.04 in salary and benefits from the University of Waterloo despite the fact that the university paid Johnston's successor $506,083.26 to do Johnston's old job that year.

In all, Johnston received $5,575,658.55 in salary and benefits for his time at UW.

All I see in Johnston is a greedy man who got wealthy off taxpayers and students, many who had to take on debt and/or work low-wage jobs for the privilege of attending university.
