When I use the .Include syntax in EF6, reverse navigation properties are always loaded. Is there a way to turn that off? Here is a sample query.

I think what you're seeing is a result of "relationship fix-up":
Relationship fix-up ensures that related objects are automatically linked when the second entity enters the ObjectContext.

In your case, since you're including AccountLocation.Address.City, EF is loading the related Address entities and the related City entites that you requested, and as part of the "fix-up" it's adding the loaded Address entities that would be part of the City->Address one-to-many relationship to the City.Addresses navigation collection.
You can find another example at this link. As in your case, lazy loading and proxy creation were also disabled -- however, that link doesn't include a way to disable this behavior.
