The article I linked lists two such examples. More importantly, my point was that in this case, although the GG chose to do as asked, that was by no means a set outcome. If she had done otherwise, as happened in 1896 and 1926, that outcome would also have been considered reasonable, and most likely not resulted in a public outcry and overthrowing the monarchy.

I still think it was a bad call allowing Harper to get away with prorouging parliament twice and giving the cons time to paint a coalition government as somehow "unconstitutional" and "undemocratic".

It's MORE democratic if anything.
