The website for Canada Pride's festival in Montreal, brags that it is the largest such pride festival in the Francophone world.

Trudeau shared this video on his Instagram.

The same day, Trudeau attended a similarly colourful festival, the annual India Day parade in Canada.

A quick costume change one imagines.

India Day officially commemorates Indian Independence from the British Empire, and occurred on 15 August.

The India Day parade was held on Sunday as the closest weekend.
