A mild winter means the maple sap is running well ahead of schedule at the Kortright Centre for Conservation in Vaughan, Ont.

Natalie Zalkind is the education supervisor there and said the early sap run is due to the mild weather and lack of snow.

"The trees are happy enough to give us sap until early April but we might finish a little bit earlier this year,” she said. Maybe all the sap is going to be all used up or maybe the weather is going to be so warm that the sap stops flowing a little bit earlier this year."

Sugar shacks in Northern Ontario have also started tapping their trees early.

Forestry experts say the last time trees were tapped this early was 20 years ago.

Ontario accounts for four per cent of Canada's maple syrup production, that's about 1.1 million litres each year.

Quebec accounts for about 90 per cent of the country's maple syrup production.
