Canute was the illegitimate son of Sweyn II Estridsson.

Because of his "martyrdom" and advocacy of the Church, Canute quickly began to be considered a saint. Miracles were soon reported as taking place at his grave. In 1101, thanks to the persuasion of Eric III of Denmark's envoys, Pope Paschal II confirmed the "cult of Canute" that had arisen and King Canute IV was canonized as a saint. In 1300, his remains and those of his brother were interred in the new Saint Canute's Cathedral.

His feast day is recognised by the Catholic Church as being on 19 January. However, in Sweden and Finland his feast day is celebrated on 13 January. This appears to be because he decreed that Christmas be celebrated for 20 days, and 13 January falls 20 days after Christmas day.
