I made this very move from the lower mainland (BC) 10yrs ago.
From a real estate perspective, it's a bit of a trap - value of farmland is going up, but residential property in rural SK is not. Just something to keep in mind if you ever want to sell and move (back) to somewhere real estate is constantly appreciating.
We have a great spot on a creek, and have not considered relocating but if I was doing it again, I'd look at the Shaunavon area, south of Maple Creek. They have oil in the region and seem to have a stronger economy than those areas that are strictly agricultural.
Kerrobert (north of Kindersley) might be worth a look too.
Kerri Finlay is a great resource when it comes to water quality and monitoring in SK.

If I'm not misinformed, the Saskatchewan Wildlife Federation is the biggest per capita wildlife federation in the world;
