Most provinces have one obvious primary city. Alberta has Calgary and Edmonton, close in size, with Edmonton the capital and Calgary the larger. Fixtures built around a single "main city per province" assumption produce lopsided Alberta data, and any UI that shows one city per province has to choose arbitrarily.
Alberta’s rural road grid uses range roads and township roads as street names in their own right. A parser that expects every street name to be a word followed by a type — Maple Drive — mishandles a name that is itself two words plus a number. Enable non-civic forms to get rural routes alongside them.
Alberta observes Mountain time while British Columbia to its west is mostly Pacific and Saskatchewan to its east does not change its clocks at all. Three adjacent provinces, three different behaviours. If your application derives an offset from a province code, Alberta and Saskatchewan together are the pair that breaks it.
Alberta charges GST only, where most provinces add a provincial or harmonised component. Any tax calculation keyed on province needs an Alberta record to confirm the single-rate path is exercised, and it is a common place for a default to silently apply the wrong rate.
Every Alberta postal code begins with T, covering the whole province from Calgary and Edmonton to the far north.
Range roads, township roads and concession-style names are part of the Canadian rural road grid and appear in Alberta addresses. They are included precisely because they break address parsers written for city streets.
Yes. Both are in the city filter, along with Red Deer and Lethbridge, and both work through the API with the city parameter.
No. Records carry a province code and a province type, which is what a tax rule should key on. The rates themselves belong in your application, not in synthetic address data.
Every record is synthetic, generated for development, QA, testing, demos and staging. These records do not represent real people, and the addresses are not verified deliverable addresses.
