In terms of commenting on the substance of the Mayor's conduct, here is my take:
1) Insofar as his conduct was lawful; and involved a consenting adult, one no longer in the City's employ, and it had no tangible, adverse effect on his management of the City.......... I don't care.
2) I don't know what arrangement he has or has not had with his wife; and that frankly is none of my business.
3) Men like sex, powerful men with money often get opportunity thrown their way quite regularly, and very often take advantage of that; is this sometimes unwise or ethically suspect? Quite probably, however, its worth saying,
if John's conduct is the litmus test for holding power, several politicians more powerful than he are due for immediate resignation, and so are a few members of council.
4) I don't hire (vote for) any politician, irrespective of their sex or orientation based on whom they do or do not have an intimate relationship with......... unless the act is directly linked to something illegal or corrupt, I don't care. I care what you do or not achieve in your job.
5) Is having a relationship, even a consenting one, with a subordinate, illegal? No. Is it generally contrary to most human resource guidelines and almost certainly a suspect idea? Yes. However, there are countless suspect ideas pursued by people at all levels of society, economic and social that are dubious, if they all had to resign over such where it wasn't impacting their job performance, I suspect 97% of jobs would be vacant.
6) John Tory was a profoundly under-achieving Mayor, who by way of not-so-benign neglect in some measure, and by actively spending too much on IMIT and the Gardiner rebuild served to see an overall decline in quality of life, with diminished infrastructure, more crowding, more homelessness and not much to show for all that either. I will not miss him. However, I will not miss him for those reasons immediately above and not for his sexual indiscretions.
