A popular plaza in downtown Ottawa has been renamed in honour of a former mayor who touched the lives of many.

Marion Dewar's family was joined by politicians and friends at a ceremony on Friday to rename Festival Plaza outside Ottawa City Hall.

"May mom's spirit sing, laugh and dance here for all times," said Elizabeth Dewar, who thanked the city on behalf of the Dewar family.

Dewar served as Ottawa mayor from 1978 to 1985. One of her many accomplishments included a program called Project 4000, where she arranged for Vietnamese boat people to relocate in the capital.

Dewar passed away in hospital on Sept. 15, 2008 after suffering a serious fall. She was 80 years old.
