Well this is an old thread but I've done some research and came upon the Saint John Municipal DRAFT plan which was released on June 7th of this year. Basing myself on the future land use map, it looks like the City has no plan to allow development near Cedar point in the next 25 years. The whole area around Cedar point can be seen in green which means 'Parks and natural areas'.

It's not a zoning by-law in the sense that it is not legislation, but more of a direction the city wants to take in terms of planning and development. The Common council (Municipal council anywhere else in the world) of SJ ultimately decides who can develop and where. Based on their land use plan, it would be irresponsible of them to permit development in an area defined as 'Parks and natural areas'.
In this municipal draft plan, Park and natural areas are defined like this :
Parks and Natural Areas are not identified for development, in order to conserve ecosystems and the natural environment. These are areas that are currently in a primarily natural state; are not appropriate locations for development; or would benefit from re-naturalization (conversion back into a natural state) including wooded lands, lakeshores, rivers, coastlines, and important geology and habitats. The lands identified as Parks and Natural Areas are intended to form a system of natural areas to conserve ecosystems through specific policies in the Land Use Chapter, such as the provision of wildlife corridors, protection of Environmentally Sensitive/Significant Areas, and guidelines for watersheds, riparian, coastal and estuarine areas.

Let's cross our fingers the plan stays as is and there should not be any access issues for Cedar point at least for the next 25 years!!
If someone has more info please come forward. I have some experience with land use plans and their legal aspects, but again I am not a City servant and therefore am not an expert on the subject.
