"When an organization or a visitor would approach us with a new possible activity or event, the easiest answer for us to give was 'No,' said Ed Jager, Parks Canada director of visitor experience. "That's the culture we're trying to change."
This spring, Parks Canada completed a four-year review of activities it would allow in areas it controls.
The sport of geocaching, a sort of GPS-guided treasure hunt, got the OK in 2009. Mountain biking, kite surfing and zip lining were all approved over the years and hang-gliding and paragliding were given the nod in February.
Managers at each park now have the authority to decide how those activities fit their environments.
Mountain biking has already been expanded at parks across the country. Kite surfing is an addition at parks in Prince Edward Island, Manitoba and Alberta.
A decision on a via ferrata — fixed cables and rungs allowing non-experts to cross an exposed mountainside — for Mount Norquay at Banff National Park will be made in the coming weeks.
Canopy tours, which use zip lines to take visitors through a treetop environment, are also being considered.
And paragliders are panting at the thought of soaring along mountainsides and over lakes.
"It would be a great opportunity for us to go into some of the most beautiful areas in Canada," said Bruce Busby of the Hang Gliding and Paragliding Association of Canada. "We're champing at the bit."
The new activities will increase private business involvement in the parks. Via ferratas and canopy tours would be offered by for-profit operators, said Jager.
"People would pay a fee and we would make sure it was a very safe experience for visitors."
The idea, he said, is to keep an increasingly urban and immigrant-based population connected to its natural heritage.
"These activities can, in some cases, if done properly, provide great opportunities for people to connect to these places,"said Jager. "It provides visitors with a perspective they would normally never have."
But allowing such activities in the parks risks making thrill-seeking the lure, zipping through the forest rather than experiencing the trees, said Alison Woodley of the Canadian Parks and Wilderness Society.
"Are they really connecting people to these places in ways that allow them to build that culture of conservation in Canada?" she asked. "Some of these activities, it's not clear they're connecting people with nature."
She also points out that budget cuts at Parks Canada are inhibiting the agency's ability to monitor the results and effects of their decisions.
"Canadians really love their parks as wild places and they want them protected as wild places. We have to make sure we don't cumulatively damage that."
Jager said any new activities would have to include an interpretive element to them.
"The experience must be guided and interpreted. That's part of trying to create the framework so the experiences are about all aspects of Parks Canada's mandate."
The next stage for Parks Canada is considering mass events, Jager added.
A bike race that drew 1,500 riders in Banff last year has been given the go-ahead for a second run. Other events such as mud races — a type of obstacle course/cross-country run — are also under consideration.
Balancing wilderness values and human use is a fine line, Jager acknowledged.
"They're complex issues and you have to make sure you get it right — right for now and right for your great-great-great-great-grandkids."
