A good example. They only list (commonly) four municipalities in Ontario for in-person, two in GTA, Ottawa, and Kitchener.
Kitchener does typically have them on mondays, so that would make sense. But I don't know if they invite people from Guelph to Kitchener ceremonies - easy enough by car, a challenge by public transport.
It's not excluded that they have in other localities from time to time - it's a bit surprising to me they don't have somewhere covering further in south-western ontario (eg London, Windsor, Sarnia) or somewhere further north. But I don't know about their practices for that. At any rate, if they were to hold ad hoc ones to fill gaps, Guelph would probably not be a priority. (Although maybe special occasions....)
