Sphaerophoria male
Hello Robin,
This is a male of the syrphid genus Sphaerophoria.
I can't give you a firm ID, because for the correct identification you will have to look at their genitalia.
I can tell you that the the genus is widespread, and in your part of the world there are 13 species!
Greetings,
Gerard Pennards

Sphaerophoria
Thanks, Gerard. There's 9 species recorded from Ontario, and some of my Sphaerophoria photos look obviously different than others but I've come across no similar web images IDed to species yet.
