Advice converting geogratis data to Google format

[Jennifer Bell]

Hi,

My friend is looking for advice on how to convert neighborhood boundary data from the 2001 census, courtesy of geogratis, to a format useable by Google Maps.  He's buiding a FixMyStreet.com-like tool,  and would like to enable relating problem reports to neighborhoods/municipalities.   The value of this data set is that it has that boundary info, as census subdivisions, for all of Canada, all at once.  I've posted his question below.  

It would be nice, generally, to have this info easily available for use in any Google Maps mashup.  I notice there's Federal Electoral boundary info there too.

Ideas for alternate data sources or approaches are welcome.

I'm trying to convert the Population Ecumene Census Division Boundary
File (http://geogratis.cgdi.gc.ca/geogratis/en/option/select.do?
id=426) from its e00 format to a series of WGS84 lat/lon points.

I've tried doing this by first converting the e00 file to a shapefile
(using the steps here:
http://freegeographytools.com/2007/converting-e00-vector-data-to-shap...)
, then using MapWindow GIS to reproject the data to WGS84, and then
exporting the shapefile to .mif lat/lons using FWTools ogr2ogr.exe.

However, the coordinates I end up with won't successfully map in
Google Maps.

Any ideas? Is there an easier way to do this? My end goal is to get
these polygons into a MySQL database using the geospatial extensions.

For Google Maps, I'd try ogr2ogr or some of the other tools that now
exist for "Shapefile to KML conversion".

Although you don't need KML for Google Maps it does support it and as
a bonus you'd get Google Earth too.
