Comment 3 for bug 368056

As Etienne said, fr_CA is pan-canadian. So I googled the gc.ca domain in search of an official French document on which we would get a definitive answer.

I found several occurrences where the first day of week is Sunday and none where weeks starts on Monday. But, I couldn't find any official document where this definition would applied outside the scope of the document itself.

Even though I didn't find an official definitive answer, I find at least one law that defines a week as starting on Sunday in its French version:

"« semaine » Période de sept jours consécutifs commençant le dimanche, de même que toute autre période prévue par règlement." -- http://www.servicecanada.gc.ca/fra/ae/legislation/ae_lois_item_2.shtml

Does anybody knows an official document that can answer this question?
