You know, if it goes in column B or column A, it may have no impact whatsoever. On the other hand, putting it in column A or column B may have either an impact on the current payment, or have a precedence value. I'm not familiar enough to know what the mistake was and what the correction is to know whether there is in fact, as you say, no impact. I would have thought that for a correction of some significance you would at least have had some exchange of correspondence with the Province of Ontario.
