OTTAWA - Prime Minister Justin Trudeau says he's "deeply grieved" by Tuesday's terrorist attack in New York City.

A man in a rented pickup truck mowed down pedestrians and cyclists along a busy bike path near the World Trade Center memorial, killing at least eight and seriously injuring 11.

The driver barrelled along the bike path for the equivalent of about 14 blocks before slamming into a small yellow school bus.

In a release, Trudeau offered sincere condolences on behalf of all Canadians to those mourning the loss of family members and friends.

He also offered wishes for a full recovery to those who were injured.

NDP Leader Jagmeet Singh took to Twitter, tweeting "Sending my love, thoughts and prayers to all those impacted by the tragic violence in Manhattan today, along with all first responders."

Conservative Leader Andrew Scheer released a statement on Twitter condemning the attacks that he says are meant to inspire fear and added 'Our prayers are with the victims and their loved ones.'
