I live in Ontario, Canada and have been tagging for 10 years. A few years ago a colleague informed me that the Ontario Ministry of Natrual Resources (MNR) requires that we obtain a "Wildlife Scientific Collector's Authorization Licence" each year for the tagging season. It does not cost anything but each year I begrudgingly do it. Still, it seems to be a bit much for just tagging Monarchs. Anyone else have to be "legal' to tag?????
