Well, it's on the opposite side of Calgary from Cochrane, but Eagle Lake near Strathmore has some pretty good pike fishing. Shallow, warm, weedy...pike paradise. After work one day, I went there with a friend and a very leaky canoe. In 90 minutes the pair of us caught 45 pike and one walleye.
Catch and release of course!
We might have had five or six of those fish that were under five pounds. No "monsters", but consistently getting hits on almost every cast. I'd swear that those pike would have chased our spoons right into the canoe if they could figure out how...I caught one when the spoon was less than ten feet from the end of my rod.
If you're running ten pound test, you're probably okay...but I'd make real sure that you've got a steel leader.
