As far as large bears go, the black bears on Haida Gwaii (Formerly Queen Charlotte Islands of B.C.) off our West coast run large as well.
I saw one on a logging beam scale in "Jescatla" (logging area on Graham Island) that was 875 pounds. Their meat diet is pretty much salmon
and deer, just about all year long, both being plentiful on these islands along with lush vegetation when that is what they are eating. The
tidal pools on the coast have them eating shell-fish & other aquatic life as well, when desired.
