A video circulating on social media purported to show Canadian Prime Minister Mark Carney announcing a new vehicle policy that might have vintage and classic car owners clutching their keys.

The video viewed more than 5 million times across X and TikTok showed Carney explaining a new policy to rid the streets of cars older than 25. Carney’s Liberal Party won Canada’s April 28 election.

"Effective June the 1st, all vehicles manufactured before 2000 will be gradually phased off Canadian roads due to safety and emissions standards," the video showed Carney saying. "Noncompliant window tints, including rear windows, are now prohibited. Drivers will have a 14-day grace period to install approved replacements."

The earliest version of the video we found on TikTok was posted May 3 with a caption that said: "​​Mark Carney announces some new Motor vehicle laws what’s everyone’s thoughts? Audio from @Fish Audio." The company Fish Audio provides artificial intelligence speech features like AI voice over and voice cloning. A small label at the bottom of the post identified the video as AI-generated. It has since been deleted.

But posts like this spread without clear disclaimers that the audio they stemmed from wasn’t real. One TikTok user posted a May 4 video, saying, "I hope you don’t have a vehicle that’s before the year 2000, because as of June 1 they’re being phased out. Goodbye older vehicles." That video received more than 1 million views.
