270 is king! But hey I'm in the same boat as you here in SW Ontario. I will toss is a curve for you...look @ 6.5 creedmoor it will do both well. The 243 is a great varmint round and perfect for yotes and wolves, but Northern bucks...no way. My 2 cents
its actually Very reasonable approach! although to split the Difference beautifully , the 260 Remington is His Man!
