So Far, So Good
Wintering in southern Ontario, this White-throated Sparrow is very close to the northern limit of the species' typical winter range. This particular bird also has a significant underbite, however, s/he seemed to feed successfully without any obvious difficulty, and preening must not be an issue since her/his feathers were in good condition. It's probably helped that s/he has found a location where food is plentiful.
