The terrorist attack left six men dead and five others seriously wounded.
The anniversary is also the first National Day of Remembrance of the Quebec City Mosque Attack and Action Against Islamophobia, which was proclaimed last April.
Due to COVID-19, the event is largely virtual again this year, with speeches being made outside the mosque in Ste-Foy, a suburban borough of the provincial capital.
Quebec Premier François Legault and Quebec City Mayor Bruno Marchand are among those expected to attend the evening event, with the public asked to follow online.
A lone gunman shot and killed six Muslim worshippers shortly after the end of evening prayers on Jan. 29, 2017.
The ceremony is one of several events organized by the Quebec City Islamic Cultural Centre and community groups this week.
