Recently someone asked for a Canadian French keyboard layout, and to my surprise I found that there are at least 3 of them in use, all quite different. Apple provides Canadian French - CSA with OS X, and another one, Canadien Français, with a Quebec flag icon, can be found here. Finally, there is the Canadian French which Apple provided with OS 9. You can get this one from my iDisk.
This graphic shows the differences in the layouts.
