TORONTO — Gunshots struck a Jewish elementary school in Toronto on Friday for the third time in seven months, the latest in a series of antisemitic attacks that prompted officials to announce a new push to address Canada’s rising hate crimes.

In Montreal this week, police said they were investigating an arson at a Jewish community center and synagogue that had been targeted before.

“I’m sickened by reports of shots fired at a Jewish elementary school,” Prime Minister Justin Trudeau said Friday. “This is a hateful, antisemitic attack.”

Bullet holes pockmarked the front of the school, Bais Chaya Mushka Girls Elementary School in north Toronto. Six shots were fired by a person who was shown on security video footage getting out of a vehicle that drove up to the school around 2:30 a.m. Friday, police said. Gunshots were also fired at the school in May and October, and police have arrested two people in connection with one of the earlier attacks. The school belongs to the Chabad Lubavitch movement, a Hasidic branch of Judaism.
