Knowing their policies it makes this out-of-the-blue project seem suspicious. I'm all for nuclear power especially if it's using CANDU reactors and thorium. But these guys ream the carbon tax or anything remotely environmental or socially progressive.
In Canada only Ontario (Ford) and New Brunswick (Higgs) have nuclear reactors generating electricity. Saskatchewan (Moe) doesn't have any reactors but they do have oil from the tar sands sharing it with Alberta on their border. Saskatchewan also has an abundance of uranium.
So colour me surprised and a bit suspicious these guys would push for this. Imagine if Trump suddenly swore off coal and wanted to build more solar and wind farms. Saskatchewan has more to gain than the other two premiers.
