Verifying date of ship arrival

Re: SS Labrador, Dominion Line, Liverpool to Quebec, 1893-09-21 My ancestor Wm Beaumont arrived in Canada in 1893. This is confirmed through several separate sources. But the manifest for the passenger list for above sailing states that this arrival occurred in 1895. Is it possible that the date of arrival page on the manifest has somehow been attached to an incorrect passenger list by mistake, perhaps when the passenger list was microfilmed? Has anyone encountered a possible discrepancy of this kind in their searches? Thank you. Margaret, Canada
