Are the distances and times on Vancouver Trails round-trip or one-way?

In the stats on each of the trail pages on Vancouver Trails, it will either say "Round-Trip" or "One-Way" to the left of the Trail Distance.

In general, all of the trails on the website are round-trip EXCEPT:

the Grouse Grind and BCMC Trail - It is expected that you will hike up these trails and pay to take the Grouse Mountain Gondola back down.
Hanes Valley Trail - This trail is really long and it too is expected you will end at Grouse Mountain and pay to take the Gondola back down.
Baden Powell Trail(s) - These are generally hiked one-way and then people either bus or arrange for other transportation back to their car or the city.
High Note Trail - It is expected that you will take the chairlift to the Peak, hike the trail around and return to the Whistler Gondola.
Sea To Summit Trail - The trail in Squamish ends at the top of the Sea To Sky Gondola and you can purchase a download ticket to get back down the hill.

All of the other distances and estimated times are from the start of the trail and back again.
