Great news for park enthusiasts – the Liberal government is making entry into national parks and historic sites free in 2017 as a way to mark Canada’s 150th anniversary, reports the Calgary Herald.

In an emailed statement, Parks Canada said this offer applies to any passes purchased this year and is valid for two years.

“As a first step towards celebrating Canada150, Discovery Passes for 2016 will be valid for 24 months rather than 12 months,” said Parks Canada’s Natalie Fay. “All Parks Canada Discovery Passes purchased in 2016 will be valid for 24 months from the date of purchase. The passes will incorporate the purchase of one year’s admission and free admission to Parks Canada places in 2017.”

Free entry to national parks was first mentioned in Prime Minister Justin Trudeau’s mandate letter to Minister of Environment and Climate Change Catherine McKenna. According to the letter, Parks Canada could also make admission for children under 18 free as well as provide any adult who has become a Canadian citizen in the previous 12 months with a year’s free admission to the national parks.

Fay alluded to other plans to celebrate Canada’s 150th anniversary.

“Exact details on any new initiatives are still being determined and will be announced in due course,” she said.
