"...in all yous guys command..." or some such variant would work around here and no one would notice.

O Canada does have other verses, as mentioned above, one which contains the line "may stalwart sons and gentle maidens rise".

My favourite verse:

O Canada! Where pines and maples grow,
great prairies spread and lordly rivers flow,
how dear to us thy broad domain,
from east to western sea,
our own beloved native land,
our true north strong and free!
etc...

But wait, perhaps it's not inclusive enough for oaks, spruce, cedar et al.

Peace, Mooh.
