On 16 June 2012, the stage collapsed during the setup for a concert by the English rock band Radiohead in Downsview Park in Toronto, Canada. Drum technician Scott Johnson was killed and three other members of Radiohead's road crew were injured. Radiohead and other recording artists offered tributes and condolences. In June 2013, Live Nation Canada Inc, two other organisations and an engineer were charged with 13 charges under Ontario health and safety laws. The hearing began in June 2015, but a mistrial was declared after the judge was appointed to Ontario Superior Court and lost jurisdiction. The case was dropped in September 2017 under the Jordan ruling, which puts time limits on cases. Radiohead condemned the decision. In 2019, a Canadian inquest found that the roof had not been strong enough to support the stage equipment and returned a verdict of accidental death. A British inquest held later that year found that inadequate technical advice and construction techniques had caused Johnson's death.

Downsview Park is a large urban park located in the Downsview neighbourhood of Toronto, Ontario, Canada. The park's name is officially bilingual due to it being federally owned and managed, and was first home to de Havilland Canada, an aircraft manufacturer, and later was a Canadian Forces base. The park still contains Downsview Airport. In 1999, the Government of Canada declared it as "Canada's first urban national park." However, unlike the Rouge National Urban Park in eastern Toronto, Downsview Park is managed by the federal Crown corporation Canada Lands Company rather than Parks Canada. As of 2017, little development has taken place, and the park remains mostly untouched.

The 17th World Youth Day 2002 (French: Journées mondiales de la jeunesse 2002) was a Catholic youth festival held July 23 to 28, 2002, in Toronto, Ontario, Canada. World Youth Day is a celebration of faith begun by Pope John Paul II held on an international level every two to three years, and WYD2002 was the 10th such event. Although WYD is designed for Catholics, it attracts sizable numbers of youths from other faiths and denominations and was presented as a multi-faith celebration of young people from all over the world. As the event is ultimately an expression of faith, and a critical expression of faith is through service to others, World Youth Day 2002 had the support of some 25,000 volunteers; and some 100,000 pilgrims themselves spent three hours each on one of 750 service projects. The groundswell of Catholic spirituality following World Youth Day 2002 in Canada led to the establishment of Canada's first national Catholic television network, Salt + Light Television. Fr. Thomas Rosica, who was the National Director of WYD2002, is also the founder and Chief Executive Officer of this new television station. For the third time (after Buenos Aires 1987 and Denver 1993) the World Youth Day was celebrated in the Americas. The Chief Executive Officer and National Director of these WYD was Father Thomas Rosica.
