After his flight landed at Winnipeg's Richardson International Airport at around 2 a.m. Saturday, Humphrey moved into his temporary home at the zoo's International Polar Bear Conservation Centre, according to officials.
"Humphrey arrived safe and sound and is adjusting to his new surroundings," Dr. Brian Joseph, the zoo's director of zoological operations, said in a news release.
"All signs indicate that he is in good spirits and it will be a smooth transition as he is slowly introduced to the other polar bears."
Humphrey explored his temporary digs at the International Polar Bear Conservation Centre on Monday.
He will remain in quarantine there for 30 days, which officials say is standard procedure.
Humphrey is the younger brother of Hudson, one of the Winnipeg zoo's resident polar bears.
Both Hudson and Humphrey share the same parents and were the only surviving cubs in their respective litters. Both cubs were closely monitored by Toronto Zoo staff in the early stages of their lives.
The Assiniboine Park Zoo now has a total of seven polar bears. There are two other cubs — Blizzard and Star — along with Hudson and three other adult bears.
