Daniel met his wife Marinette in his hometown Örnsköldsvik around 1998. She came with him to Vancouver upon the start of Daniel's NHL career in 2000, and the two married in 2005. After earning a bachelor's degree in psychology at the University of British Columbia Marinette became involved with the Canucks Family Education Centre, helping female immigrants transition to the English language. Together, they have two daughters, Ronja (born in 2005) and Anna (born in March 2011), and a son, Erik (born in 2008). They live in the Vancouver neighbourhood of West Point Grey during the NHL season, returning to Sweden every summer.
