Already a bit of a celebrity online — watch some of his most memorable moments here — the cub now has an A-list name to match: Humphrey.
Humphrey was born in November. And just as zoo officials let fans name Hudson, Humphrey's older brother who now lives at a the Assiniboine Park Zoo in Winnipeg, they set up a "name the cub" contest for little Humphrey, too.
More than 14,000 people voted on the cub's name.
Others names in the running were Orson, James, Lorek, Searik and Stirling.
He will be formally documented as "Humphrey Piujuq" in the official registry at the zoo. "Piujuq" is an Inuit name meaning "good and nice."
"I am very proud to be a part of Humphrey's incredible journey, as it is one that exemplifies the passion and dedication of the Toronto Zoo's Wildlife Care, Wildlife Health Centre and Nutrition Teams," says Jeff Young, Supervisor of Americas. "The Toronto Zoo saves and protects animals and their habitats at home and abroad, and Humphrey is a wonderful result of this continuous commitment."
The zoo believes Humphrey will be a great "Arctic ambassador" for the vulnerable species, helping to spread the word on how to protect "Canada's national treasures."
Visitors can see Humphrey at the Toronto Zoo in his outside den and polar bear maternity area from 10:00 am to 4:00 pm daily.
