Hello Mark
My favourite Shorebird location when I was more mobile used to be the Townsend sewage lagoons in the Jarvis area. This is one of the prime Shorebird locations in Southern Ontario.
Many very good Shorebirds have been seen at this location in the last few years including Black-necked Stilt, A. Avocet, Curlew Sandpiper, Hudsonian and Marbled Godwits, Whimbrel, plus all the usual Shorebirds.
This is also a great place for other birds and my own list includes Eared Grebe, White-fronted, Ross's, Snow and Cackling Geese, Franklin's, Little and Sabine's Gulls, Grey Partridge, Western Tanager, Lapland Longspur and many more. My life list at these lagoons is 135 species and I highly recommend visits to these lagoons from Mid August to November and March thru May.
Thousands of Geese, Tundra Swans and Ducks rest at these lagoons during March and April each year and are a sight and sound to behold. The number of waterfowl is lower in the fall but still impressive.
Below are the directions to the lagoons.
I also like Frenchmans Bay, Cranberry Marsh, Hydro Marsh in Ajax, Second Marsh and Cootes Paradise in Dundas. These 5 locations are close to Toronto as you may know and Townsend is just about an hour away.
