Prince Philip is planning a lightning trip to Toronto this spring.

The Duke of Edinburgh will travel to the city on April 27 to present a new regimental colour to the Third Battalion of the Royal Canadian Regiment.

It’s his only engagement during what Ottawa describes as a “private working visit.”

The prince has served as the regiment’s colonel-in-chief — an honorary title often bestowed on members of the Royal Family — since 1953.

Regimental colours are a kind of ceremonial flag considered the most prized possession of every regiment.
