These creatures have either died out entirely or are extirpated from Canada, meaning they no longer can be found in this country, but have survived elsewhere:
1. Hadley Lake stickleback (1999): A fish that was only found in Hadley Lake on Lasqueti Island in B.C.’s Strait of Georgia, the stickleback had only been discovered in the 1980s, but was completely wiped out by the introduction of catfish.
2. Karner blue (1991): A small blue butterfly that existed in the area between Toronto, London and Sarnia, the Karner blue no longer exists in Canada due to habitat change and loss of the larva’s only food source, the wild lupine.
3. Frosted elfin (1988): Another butterfly, the frosted elfin was only discovered in 1960 and the population may have only ever numbered 100. But they’re all gone from Canada now due to habitat loss.
4. Greater prairie chicken (1987): Once abundant in Ontario, Manitoba, Saskatchewan and Alberta, this large grouse, known for the bright orange featherless patch on its neck, vanished from Canada due to hunting and habitat loss.
5. Banff longnose dace (1986): The tiny freshwater fish only existed in a marsh in Banff National Park. It was done in by the introduction of tropical fish, chlorine leaking from a pool and a beaver dam.
UPDATED: The black footed ferret disappeared from Alberta and Saskatchewan in the early 20th century, but was reintroduced in Saskatchewan’s Grasslands National Park in 2009. A Sept. 2012 count found at least 12 of the cute little guys in the park. Here’s the video evidence.
6. Black-footed ferret (1974): Little is known about this particular type of weasel but it’s believed to now be extinct in Canada.
7. Striped bass (c. 1968) (St. Lawrence Estuary population): Fished out of existence, there are efforts to reintroduce the species.
8. Blue walleye (1965): Once a common fish in Lake Ontario and Lake Erie, it was overfished out of existence. The last confirmed blue walleye to be caught was nearly half a century ago.
9. Lake Ontario kiyi (1964): A deepwater fish, it is now extinct from overfishing.
10. Greater sage-grouse (1960s): Once common across the Prairies and B.C., this bird, known for its elaborate courtship rituals, has vanished from Canada.

Have you ever wondered which cities have the most bars, smokers, absentee workers and people searching for love? What about how Canada compares to the world in terms of the size of its military, the size of our houses and the number of cars we own?
