Don't have a shapefile, but the old CMDA masterplan was the only clear map of the ward boundaries that i've seen: https://www.cmdachennai.gov.in/Volume2_English_PDF/Chennai-StreetAlign.pdf <https://www.cmdachennai.gov.in/Volume2_English_PDF/Chennai-StreetAlign.pdf>
The best i've managed to do is to georeference a cleaned up version of the above map so it is available as a geotiff. One would need to manually trace out the lines in QGIS to create a shapefile which could be a bit tedious, but the only way if you really need it. https://mapwarper.net/maps/77607#Preview_Rectified_Map_tab Would be great to know why the sudden interest in the pre 2011 ward boundaries.
