May not be C. sayi--C. calidum or C. frigidum
I do not think the range of Calosoma sayi extends into Canada. I believe this is probably one of the other, similar, Calosoma species, such as C. calidum. There is a Ground Beetles of Candada web site with many photographs of specimens, see this link. Looking at that page, it looks like C. calidum or C. frigidum to me, displayed here, I hope. The punctures on the elytra look like. C. frigidum in those specimens, I don't know if that is diagnostic.

Yes, they are fast--good job getting a photo of one on the run--I've had to capture Calosoma to get any photos.

I'll move this up to the genus level for now. Perhaps someone familiar with northern species can help.

We cropped the image so it would look at least a little larger on the screen for visitors. Hope that's ok.
