Moved from Ogcodes.

Jason, this goes to Ogcodes canadensis in the key to nearctic species on pg. 274 of:

Schlinger, E. I. (1960). A revision of the genus Ogcodes Latreille with particular reference to species of the Western Hemisphere, Proc. US Nat. Mus., 111(3429): 227-336, 9 figures, 13 plates (Full Text)
Although the main wing venation character in the first couplet of that key (referring to the presence or absence of vein M1) was not clearly discernible to me in the photo, critical characters for assessing the subsequent couplet choices were apparent (though I had to "zoom in" on the image using my browser by repeatedly pressing "Cmd-+" on my Mac (try "Cntl-+" if running Windows)). Following both alternatives at couplet 1 led to an inconsistent dead end with one choice (i.e. couplet 18), and to a strongly consistent conclusion with the other choice (i.e. couplet 2, leading to O. canadensis). The details of the keying sequence are summmarized below, starting from couplet 2 in Schlinger's key.

    2b) Cross vein m-cu absent.....8
    8b) Mesonotal disk not patterned, ground color black.....11
    11b) Dorsum of abdomen with even fasciae (not reddish with black triangular spots).....12
    12b) General habitus black; humerus, postalar callus, and scutellum black.....13
    13b) Abdominal tergites black with very narrow white posterior fasciae covering about one sixth of segments.....14
    13b) Thoracic pile short, whitish yellow; [...]; squama opaque white except for dark brown circular spot covering basal one third; [...], Canada.....canadensis

The description on pg. 307 of Schlinger (1960) is in good agreement with (what can be seen in) your image...in particular: the thorax is shining black; the legs are black except for brown fore and mid tibiae; the wings are hyaline; the squama (small round membranous disk just below wing base) is opaque white with a large dark brown basal spot; etc. Schlinger notes that the opaque whitish squama with brown basal spot is distinctive of this species within the genus, and it's quite apparent in the image here (zoom in to see it better). The type location is "Houghron" (=Houghton?), Ontario and a paratype is from Ottawa...so your Ontario location is also a good fit.
