UJA has been organizing the walk since 1970, but the event has been subject to more scrutiny since October 2023, when the terrorist group Hamas launched a deadly attack on Israel. The assault left about 1,200 people dead and hundreds taken hostage. Israel responded with air strikes and a ground offensive in the Gaza Strip, killing more than 70,000 Palestinians. Ahead of Sunday’s walk, Toronto police said they expected counter-protesters at the walk as there have been in the last few years.
