I was like, "that's crazy, like what would that logo even look like, a Mountie? A woodsman in flannel?" - because there's no image on the wiki article.
Then I found this old article which contains the funny backstory, and explains its definitely a woodsman, and used to be a pine tree..
“Look, I was always embarrassed by our symbol,” says assistant principal Ralph Sorrentino, a North Plainfield football player in the ’50s. “We had a mascot dressed as a tree. South Plainfield had a tiger.” It was a particular problem when they played the Metuchen Bulldogs. “You know what dogs do to trees,” he says.
So in the early 1970s North Plainfield’s teams became the Canucks—woodsmen who cut down trees.
