The CMS at least has the accents but it's horrible even for this Frenchie... Canadian French is in every way better (for FRENCH Canadians; IMHO and I assume). Though both are software. There's English Canadian too in there.

In Canada, the keyboards you'll find are either US layout or ISO CMS layout. I used to type on CMS with AZERTY french settings and just used the AZERTYUIOP as the home row: had the Enter close enough and all vowels in 1 row it just sucked that the shift keys were further.
