Justin Trudeau has again apologized to racialized Canadians for another racist incident from his past, while leaving open the door that more damaging photos could surface.

The Liberal leader spoke to reporters in Winnipeg hours after Global News published a video of a younger, long-haired Trudeau wearing blackface. The grainy footage shows Trudeau opening his mouth and thrusting his arms in the air while wearing makeup that makes his skin look black.

A Liberal spokesperson told HuffPost Canada in a statement the video dates back to the early 1990s.

Trudeau acknowledged Thursday that his actions have hurt Canadians who face intolerance each day. As the son of a former prime minister, he said his layers of privilege kept him from seeing that at the time.
