french canada keyboard missing

[carmima]

Hi there,
I am setting up my new computer with bulleyes and xfce.
I need the canadian french layout because it is the only way to enter ùìôÀÊ and other accented symbols çÇ and so on.
The only way I found to get the keyboard layout I used to know and I need is with a command line:

THIS WORKS:
setxkbmap "ca(fr)"
or
setxkbmap ca -variant fr

I tried everything else, but it seems that french canada is missing.

localectl list-x11-keymap-variants ca
eng
fr-dvorak
fr-legacy
ike
multi
multi-2gr
multix

the same keyboards are listed in the applications/setting/keyboard applet.
the applet list the same 7 options, "french canada" is also missing there.

can someone tell me how to setup my system with canada french keyboard ?
I would really like to enable left alt + left shift keyboard layout switching between english/US and ca(fr)
thanks for your help

I can't find it either but MX Linux has it. I'm sure Debian has it too but it doesn't show in the installer.
