Marty Carr was born in Ontario and lived in Prince Edward County until 1982 when her family moved to Edmonton, Alberta. She attended University of Alberta where she graduated with a B.A. (Major: French language and literature) in 1994. In 1997 she moved to Quebec City to undertake an M.A. in Applied Linguistics from Laval University. She moved to Ottawa in 1999 and settled in Alta Vista in 2004.
While raising her children (Molly and Henry) with her husband (Chris) in Alta Vista, Marty became deeply involved in the community - with school councils, community groups and eventually as President of the Alta Vista Community Association. While she balanced her community work with a rewarding career in the Federal Public Service for over twenty years, it was her passion for the community that led her to run for Councillor for Alta Vista.
