Get a rocket blower and do a manual clean. Set it up in the menu for the mirror to flip up with a manual clean and give it a good going over with a blower, but just be sure not to touch anything inside the body. If it persists you may need to take it in to have it cleaned if you don't feel up to doing it yourself, but it's pretty straight forward once you get used to it.

Usually your auto sensor cleaning will be able to get the small guys off, but not the big pieces. Use a rocket blower and it should come right off. In the future if you are wondering whether something is dust or not, shoot a blank sky at ƒ22 and the dust, if any, will be very pronounced.

given how large it is in the image, it could also be dust on the rear element of the lens.

This is what I was thinking as well....assuming that is NOT a crop image..?

check your rear element, if clean, then it is definitely in/on the camera/sensor/filter!

Use a rocket blower like suggested already, should come off with no problem..worst case, send it to Canon for a clean(IIRC it's only $30, someone may know better(I have a CPS account though...so I may be completely off..lol))

Good luck!

Dust on sensor?

If you were from Roswell, NM or anywhere in Arkansas, it would be UFO evidence. I vote for dust, though.
