== Hamilton categories == 

 Just for future reference, the rule for city-specific topic subcategories is that they have to be located at the same level of disambiguation as the city's main eponymous category, regardless of whether parallel categories exist for other places of the same name or not. The uniqueness or non-uniqueness of a category's name in isolation is not the only relevant criterion when it comes to city-level categorization; we also have to give weight to consistency and predictability across the entire tree of categories related to that city. 

 That is, once it's been established that Hamilton, Ontario's eponymous category has to be at , because the numerous other Hamiltons in the world prevent it from being considered primary meaning for the plain , then any subcategory also has to be disambiguated at the "Hamilton, Ontario" level. Even if none of the other Hamiltons actually has its own dedicated subcategory for that particular topic yet, if the city's main eponymous category has to be at "Hamilton, Ontario" then all of its dedicated subcategories have to be at "Hamilton, Ontario" too whether any other Hamilton has a parallel category or not. Thanks.
