Personally I think the Carleton District should be interesting (even ignoring the fact that I live in it). It is a new riding created from parts of Nepean—Carleton, Carleton—Mississippi Mills, and Ottawa South, most of which were PC strongholds.
However, the Liberal candidate is Theresa Qadri (Councillor Shad Qadri's wife) so has a well known name.
The PC candidate (Goldie Ghamari) is largely unknown, but she has been pushing hard to get her name out there.
Grab the popcorn. Should be quite the show.
