The monkey's owners were in the store shopping when it somehow managed to free itself from its crate and escape from the vehicle.
The stylish simian was spotted monkeying around in the parking lot of the Leslie Street/Highway 401 store.
"It's a smart monkey," Toronto Police Sgt. Ed Dzingala told CBC
Concerned shoppers informed Ikea staff, who in turn notified animal control. The monkey was confined until animal control arrived around 3 p.m.
Shopper Stephanie Yim told CBC that she spotted the animal peeking at her from behind a parked car.
"It was the weirdest thing," Yim said. "I thought I was going insane."
Yim and other shocked shoppers followed the little monkey around the parking lot. She said it would "monkey-scream" from time to time.
"It seemed like it was screaming around for someone it knew," Yim said. "It was sad."
The monkey was eventually reunited with its owners, who could find themselves in trouble since it is illegal to own such animals in Toronto.
In October, a wild rhesus macaque known as the "Mystery Monkey of Tampa Bay"
made headlines after it bit a St. Petersburg woman. The animal has a cult following in the Tampa Bay area and even has its own Facebook page
