Quebec Archbishop Gerald Cyprien Lacroix was formally inducted as a cardinal Saturday at St. Peter's Basilica in Vatican City.
Lacroix was one of 19 men selected by Pope Francis to take on the senior ecclesiastical post.
Retired Pope Benedict XVI was also on hand for the ceremony honouring the new "princes'' of the Catholic Church.
The appointment means the 56-year-old Lacroix will have a hand in electing the next pope, which is a cardinal's most important task.
The native of Saint-Hilaire de Dorset, a small town 300 kilometres east of Montreal, was named Quebec's archbishop in 2011.
There are now four cardinals from Canada, with Lacroix joining Marc Ouellet, Jean-Claude Turcotte, and Thomas Collins.
