WATCH: sea of humanity and green for Montreal's 194th Saint Patrick's Day Parade

Thousands of Montrealers came out for the 194th annual St. Patrick's parade on Sunday, lining Sainte-Catherine Street as around 3,000 marchers passed by.

This year's parade counted 20 floats and about 125 different groups, who marched from Fort Street along to Phillips Square downtown - some Irish, but many more from the broader community, including the Mohawk of Kahnawake, the Shriners, and members of different Greek, Peruvian, and Caribbean communities.

Prime Minister Justin Trudeau was also at the parade, but the biggest role was reserved for Mayor Denis Coderre, who served as Grand Marshal, a tribute to his Irish maternal grandmother. 

"It is a great honour, especially this year we're also celebrating our 375th anniversary. This parade is one of the top five among St Patrick's parades."

"It's a perfect day, everything is clean, people are having fun, they're not drinking too much."

Jordan Berube marched with a group of Concordia University Irish studies students. He said parades like the one in Montreal - which has not missed a year since beginning in the 1800s - may actually be the birthplace for worldwide St Patrick's Day celebrations common now. 

"What most people might not know is that parades like this didn't actually start in Ireland. Groups like Montreal brought the parade to Ireland, that's why Dublin has the parade is has now."

Some marchers were out to have a good time, with no shortage of green sequins and public drinking, but some were also hoping to share their love for Irish arts and culture - including Kevin Wright, who represented literary and arts festival Bloomsday Montreal. 

"There's more than plastic shamrocks and green beer. There's culture, there's all kinds of authors, all kinds of movies, all kinds of cultural events that go on and most people don't know about them."
