Martha Hall Findlay looks at the prorogation angle differently than I had ever considered.
If the governor general does allow a prorogation, would it be the end of responsible government in Canada?
The premise of responsible government is that the executive remains in office only so long as it enjoys the support of the responsible house of the legislature. If the governor general allows a prorogation and sets a precedent that a prime minister can seek and receive a prorogation anytime, even when it less than two weeks after a throne speech, with no legislation passed. This would allow any future prime minister to simply prorogue whenever a confidence vote they fear losing is scheduled.
This is a very interesting and fair point. One I'm surprised I've never heard mentioned by one of the countless "experts" who've been on TV the past week.
