Looking to understand regional postal divisions within Ontario for strategic marketing, logistics, or direct mail campaigns? Our downloadable Ontario FSA Map PDF gives you a detailed, page-by-page breakdown of Forward Sortation Areas (FSAs) across the province.
What Are FSAs and Why Are They Important?
In Canada, a Forward Sortation Area (FSA) is the first three characters of a postal code. These FSAs are critical in helping businesses and marketers segment their audience by region.
In Ontario, FSAs begin with the letters K, L, M, or N, each representing a different part of the province:
K = Eastern Ontario (e.g., Kingston, Cornwall)
L = Central Ontario (e.g., Mississauga, Barrie)
M = Toronto metropolitan region
N = Southwestern Ontario (e.g., London, Kitchener, Windsor)
