How does this affect addressing protocols for other historical neighbourhoods in Markham (for example, can one start to address mail “Vinegar Hill” where they previously addressed mail Markham?
Canada Post has dual address names for many municipalities across Canada where a former municipality/ village has been amalgamated with another (e.g. Scarborough, Etobicoke, Kleinberg). This address system is referred to as the primary and secondary (viable alternative) system. Residents of other historical areas can find out if a dual address system applies to their area by visiting the Canada Post website.
