The only constituencies that Labour lost last year that are 'rural' in the sense that much of Saskatchewan is would be Ynys Môn and Stroud, and even then they are quite different. And there's no seat that Labour lost last year that it is implausible to see Labour ever regaining, especially as Labour is most unlikely to ever again go into an election with its image and priorities largely being shaped by the legacy of the (actually pretty old now!) New Urban Left. Not that this has much bearing on the politics of Saskatchewan.
I might question Stroud actually, apart from the main eponymous town and its environs you have Nailsworth, Cam/Dursley, Stonehouse - all of which can be considered reasonably "urban".
But as you say, back on topic.......
