Seams to be a released pet as discussed in this observation from 2019:
https://www: inaturalist.org/observations/31801159
In Canadian Museum of Nature. Collected by G. Wilkinson. Now extinct in Canada, last recorded in 1941 in Niagara Gorge.
Not 100% sure, looks like porcupine and would be the correct size as well. Please ID if it is something else!
American Birding Association field trip led by Brian Rapoza, and with Holly Lovell and 20+ others.
My first visit to this site, when many species of released waterfowl were still present; all but the Egyptian Geese had died out within 10 years.
To other iNatters: please do not mark this record as "not wild" in the attributes. I admit that these birds were intentionally released but I'm not aware that any was pinioned (many were metal-banded).
@raymie researched the validity of "counting" escapees/releases -- which of course is greatly confused -- but it seems that an intentionally released bird is nonetheless countable by iNat standards. A few of these records are resubmissions because the original submission got shot down to "casual" based on a majority of "organism is wild" marked with an X.
Here's the discussion that @raymie found:
