The first of course stems from the great expansion of S61 where the Grizzlies found themselves created alongside the Regina Elk. Naturally being expansion "sister" teams, it makes a valid argument for both to become rivals to each other, though unfortunately that rivalry wouldn't come to pass nearly as hard as the one initiated in Season 63. In Season 63, the Grizzlies had the best seasonal and post-season run in the franchise's history making it all the way to the finals against...Newfoundland. Now, the Berserkers aren't strangers to being major rivals of other SMJHL teams, but in losing in the finals to an extremely stacked Newfoundland team, the Grizzlies found a new rivalry that superseded the one with the Elk, and throughout the next several seasons after that finals loss, the Grizzlies would find themselves locked in bitter battles on ice against the Berserkers, sometimes coming out on top...but many times being shut away.
