Wiarton Willie seems to think so, breaking from the ranks of his fellow rodents. He called for an early spring in Ontario.
However, I would rather rely on something else, like the Farmer's Almanac to provide a clearer picture of when we can expect decent weather.
According to Ol' Faithful, we start to run into mild temperatures the second week of March. But expect the battle between winter and all things green to see-saw into April as it does most every other year to be on the safe side.
To put all your trust in a fury marmot is not an effective strategy. I would suggest to keep an eye on the weather trends as previously stated, and send the groundhog novelty act back into hibernation.
