Now that just might be a typo, but if it isn't, then it shouldn't work.
Lower down your realm is 'EXAMPLE.AD.CA' on the fileserver, and
'AD.EXAMPLE.CA' on the DCs, hopefully one should be correct, in which
case, to access the share it should be something like
\\fs1.example.ad.ca\Sharename

Do you want to try again, but this time, please use the same
sanitisation everywhere.
