Which cities have the highest number of users on Ashley Madison?

Toronto, Canada tops the list for cities with the highest number of users on Ashley Madison, as per data released in the aftermath of the site's 2015 data breach. Following Toronto, other major cities like New York City and Sydney also have a notable number of registered users. It's important to note the numbers from the breach reflect historical data up until that point and the current figures may vary due to new subscriptions or users leaving the platform. Additionally, these numbers were influenced by population sizes of the respective cities as well as differing local attitudes towards extramarital affairs and online dating platforms.
