Hi, from WWFF-side of course it is ok when you work same station on different dates from same WWFF. We also had no chance to check this. So I really don´t know if there is a more restricted rule in canada, however would not recommend.
If I would check sometimes 200 logs in month on dupes on various dates I could stay at home from work.
Please talk again with Dave VA3RJ and let me know, if any action needs to be done. You can contact of course via mail would be more efficient.
