I think the 4 party leaders should have to attend a survivor camp somewhere north of the artic circle with the winner becoming our next PM.
The 4 of them should be let loose after a 2-day survivor course by our own survivor man and then be chased down by the 'Mantracker'. They will then have one week to cross Baffin island without being captured.
They can use any survivor skills, including stealing the horse of the mantracker, going to bed with the locals, or bring lots of aquevit as bribes.
I think this will a test of who is the real Canadian and who can lead us surviving and scavanging around as the 'real' economy is crashing down around us.
