An Edmonton limousine service says someone called for one of its cars to show up at the community centre where Mark Carney launched his bid for the Liberal leadership on Thursday — but the person didn't leave a name and never showed.

About an hour before Carney was set to make his announcement — and around the time reporters and guests were invited to arrive — a limousine outfitted to look like it was made by Rolls-Royce arrived at the venue.

The car's appearance at the leadership launch quickly gained traction on social media and was amplified by some prominent conservative accounts. Some users suggested that Carney himself had arrived in the limo.

Carney's campaign told CBC News that they didn't order the car and have no idea who did. They said Carney arrived in a regular car with one of his campaign volunteers.
