My latest sighting ever was at Presqu'ile Provincial Park on one November 8th. A cold cloudy day, I had waded over to Gull Island where one monarch was going nowhere quickly on this windy day, with a few remaining flowering thistles as nectar sources. Late dates for Point Pelee include: "one (extremely fresh female) on
December 4, 1982 (Michael J. Oldham, Alan Wormington); one on December 4, 1995 (Enid Bull)." There is a record of one monarch being spotted one year in Ontario during a Christmas Bird Count.
As many will have now heard, monarchs were observed arriving on Cerro Pelon and El Rosario and other locations in the Monarch Reserve on October 30th as usual and just before Day of the Dead.
