Bjenk, I was on the same impression that CSD did (used to) not always match municipal limits because of their objective (census) since in some case it would not make sense to do so for statistical purpose…

Just to make sure we are talking about the same thing: Census Divisions are higher level and more regional boundaries. CSDs are municipal boundaries (in OSM, level 8).  http://www.statcan.gc.ca/eng/subjects/standard/sgc/2011/sgc-intro
Can you give me an example of city limits that don't match a CSD or is not in the SGC? Usually, the standard for municipal boundaries are the CSDs. At least, as far as I know, this is the standard geography. When referring to actual city limits, which geographical classification is it referring to?
Sorry for the questions, I am trying to understand what is the classification used if its not the CSDs.

Bernie, I've also noticed that StatsCan boundaries seem to be a generalization of an area vs the actual city limits

      In NB there are issues with some census boundaries not matching with our administrative boundaries. The issue I am aware of was with the county boundaries. The census data that is analogous to our county boundaries included some significant deviations to prevent a municipality from being bisected by a county boundary. Please be careful that there is not a similar issue with the CSD boundaries. NB municipal boundaries can be downloaded from the GeoNB Data Catalogue For comparison to the CSD data.

Municipal boundaries correspond to census subdivisions (CSD). I have seen that many municipalities do not have a boundary yet. Is it ok if I start adding some boundaries based on CSDs? Having the boundaries is important to make extractions and analysis at the municipal level.
