Rollercoaster weather patterns this winter and spring have been a boon for maple syrup producers in the National Capital Region.

Nicolas Simard, production manager at Proulx Maple and Berry Farm in Cumberland, Ont., said this season has been especially strong.

"We've had a really good season," he said. "We actually really need the cold nights — so frost at night and in the day, between one and five degrees Celsius, is the ideal temperature."
