The most colour-complex map, for start. The PC's have nominated almost all of their caucus, with only Steve Clark of Leeds-Grenville, Jerry Ouellette of Oshawa, and leader Tim Hudak yet to be officially nominated. I think we can probably assume Hudak will probably wait until just before the writ drops and use his nomination as a campaign kick-off event.
The PC's either have a candidate nominated, or have declared candidates, in most unheld ridings in southern Ontario, although they still have gaps in the GTA (particularly the GTA West, which I find somewhat surprising considering the seats in Mississauga, Brampton, and Etobikoe tend to be swing ridings), urban Ottawa, Guelph, Hamilton, Windsor, and Northern Ontario.
Of the top 10 closest ridings the PC's fell short in in 2007, the PC's have candidates nominated in 7 of them (Nippisisng, Barrie, Kitchener-Constoga, Eglinton-Lawrence, Lambton-Kent-Middlesex, London-Fanshawe, and Oak Ridges-Markham) and have declared candidates for the nominated in the other 3 (ADFW, SD & SG, and Don Valley West). While the PC's have somewhat neglected urban Ontario, the GTA West suburbs, and Northern Ontario, they seem to be focused nomination wise on Southwestern Ontario and the east end of the GTA.
The PC's have nominated candidates in one of the seats with a retiring MPP, Bruce-Grey-Owen Sound, and have declared candidates for nominations in the other 2, Burlington and Cambridge. The PC's also have a unique sitution of an incumbent MPP facing a legitimate challenge for the nomination, with Norm Sterling, the longest serving PC MPP facing a challenge from his right with the Randy Hillier backed Jack Maclaren (who has been buying a ton of Facebook ad's) attempting to take him down.
I'll take a look at the NDP next time.
