FSA boundary map discrepency

Hi there, I have just calculated the sq km for each BC FSA shape area for a 2002 Shorelined Data and 2008 unshorelined data. Both files are from DMTI Spatial Inc. I know that some FSA's have been merged and may explain slight discprencies in data but the ones below seem too significant. Does anyone know what I might have done to cause this issue or what I need to do resolve it. Your help is much appreciated!!
