Mount Pleasant Cemetery and the Beltline separate historic North Toronto from Yonge-St. Clair, connecting Davisville, Yonge and Eglinton and "Uptown Yonge" with the more suburban Lytton Park and so on, so you can kinda "feel" the change. OTOH Davisville and Yonge/Eg are (mostly) part of the densely populated part of the St. Paul's electoral district, rather than part of North York-centered electoral districts where more suburban outlooks dominate.

What's interesting is there's an Uptown BIA north of Eglinton and a Midtown BIA at Davisville.
