Of the 1,468 Wikidata puts here, the rest have no English or French article that confirms it.

57% here, set against 38% for Canadian towns.

Arthur Burn, from 1879; the most recent birth on the list is from 2009.

Wikidata has to place the birth inside Calgary’s city limits (the city’s 2021 census subdivision), counting its hospitals and districts, and an English or French Wikipedia article has to say the same. Adult performers, people known mostly for crimes and anyone who only lived here stay off the list. Toronto, Montréal, Ottawa and the other split cities keep a birth recorded only as the city on the city’s own page, while each neighbourhood lists just the births recorded in it.

Their Wikidata record may stop at the province, point to a rural area we have no page for, or name a different town, and their article may disagree or say nothing. Only a birthplace both sources share is listed; edits to either are picked up at the next refresh.
