This giant bee flew into my office not once, but twice! Early May, Toronto, ON Canada.
Very aggressive, about 2” long, maybe 0.5” thick. Was trying to sting the windowsill, left venom where it had stung the metal windowsill. Once caught in a cardboard box it could be heard and felt stinging the box…!

Based on the behavior and size you described of the insect in this instagram image (not ideal for species identifications), we deduce this is a female Bumblebee recently emerged from Hibernation. She is a aggressive because she wants to build her hive in some abandoned underground mouse burrow or bird house.
