The internet is a wonderful place and many statements of 'fact' here can be confirmed or refuted from the official documents made available.
The Canadian Journal of Human Sexuality gives the teen pregnancy rates per thousand from the CANSIM database 1974-2003 here

In 1999 43 out of 1000 births in St John NB were to teens.
The source for this information is from the Caledon Istitute of Social Policy May 2005 which also identifies st John as one of Canada's poorest cities with a falling population and corresponding tax base and high concentrations of low-income residents in inner city neighbourhoods

In addition to the early sexualization of children, poverty and deprivation, poor educational achievement and low expectations have all been identified as key factors contributing to high rates of teenage pregnancy.
