Mysterious pink smoke appeared above Edmonton this morning, and nobody knows exactly what it's from.

At 11:30 a.m., Edmonton locals were surprised to spot eerie magenta clouds hanging in the sky. The smoke appeared in the east of the city, and naturally, Canadians were more than a little confused.

One man suggested an epic gender reveal.

These gender reveals are getting out of hand. #yeg pic.twitter.com/OIzE1hO6eF

Which seemed to be a popular theory.

While others joked that Canada was getting a pope, since white smoke is traditionally released from the Sistine Chapel when a new pope is chosen.

A new Pope has been chosen

One person even chimed in with a scientific explanation for the mysterious phenomenon.

Clearly the answer is that a cotton candy machine is on the fritz 😂. All I can think is maybe particulate in the sky and the sun reflecting makes it look pink.

While another Canadian had a more... unusual explanation.

Oh shit they cremated Barney!

But really, most Canadians were just straight-up confused by the ominous pink clouds.

What is this?! Pretty sure pink smoke/off-gassing is not supposed to be occurring on the north side? #yeg #strathconacounty pic.twitter.com/iPKrhlkN06

Some Edmonton locals were so alarmed by the otherworldly pink smoke that they called the fire department.

Fortunately, Edmonton Fire was able to arrive at the scene within 11 minutes and confirm that the pink clouds weren't actually a fire — they were coming from the city-owned Waste Management Centre on Aurum Road.

Good afternoon, #yeg! There's been many inquiries about the pink smoke from earlier today. The smoke was coming from the Waste Management Centre and our crews responded. There was no fire, the smoke has been contained, and there are no public safety concerns.

The City of Edmonton has yet to confirm the cause of the pink smoke, but locals are speculating that it could be attributed to iodine that wasn't properly disposed of during the waste management process.
