Here are a few British-ish scenes around Montreal.
Westmount City Hall – like some kind of Tudor Revival country estate
Windsor Station and St. George's Church – a bit Scottish
Redpath Street – feels vaguely like a suburban part of London
Pine Avenue – a bit of Marylebone
Gage Road – again, some generic suburban UK vibes here
Belvedere Road – a real Hampstead feel
Royal Victoria College – feels like this would fit into Bloomsbury
