Canadian keyboard defaulted for en_CA locale
In the installer, it asks you what language you speak and where you are from.
If you answer "English" and then "Canada", it defaults to offering you the "Canadian" keyboard.
This is unconventional. The Canadian keyboard is shipped by hardware manufacturers if you order a French machine. The U.S. English keyboard is shipped when you order an English one.
This is the proper behaviour:
English Canada -> U.S. English keyboard
French Canada -> Canadian keyboard
It may make sense to rename the Canadian keyboard to "Canadian (French)" or "Canadien (Français)" to make this less confusing.
