Montreal will host an international concert in September to raise awareness about the fight against AIDS, tuberculosis and malaria.
Usher, Half Moon Run, Metric and Grimes were announced Tuesday as some of the artists scheduled to perform.
Prime Minister Justin Trudeau and Microsoft founder Bill Gates are special guests who have been invited to the Sept. 17 show at Montreal's Bell Centre.
The concert is being presented by Denmark-based Global Citizen and The Global Fund, an international partnership dedicated to eradicating AIDS, tuberculosis and malaria.
The Global Fund's donors are gathering in Montreal a day prior to the event for a conference.
Canada has pledged $785 million between 2017 and 2019 to The Global Fund, a 20 per cent increase compared with its last instalment to the financial partnership.
