With Jay Hill announcing his departure and the Bloc’s Jean-Yves Roy expected to soon follow, as many as five ridings may now be officially put in play before year’s end. Pundits Guide circles December 13 on the calendar.

Those by-elections would include two Conservative seats (Prince George and Dauphin), one NDP seat (Winnipeg-North), one Liberal seat (Vaughan) and one Bloc seat (Haute-Gaspesie). The latter three would seem to be the most worth watching—Haute-Gaspesie a narrow Bloc victory in 2008 and the Conservatives seemingly eager to pick up Vaughan.
