Johnston Canyon ist eine Schlucht im Banff-Nationalpark in der kanadischen Provinz Alberta. Sie liegt am Bow Valley Highway , dem Alberta Highway 1A, zwischen Banff und Lake Louise. Die Schlucht wird durch den Johnston Creek geformt.
Der Beginn des Weges in der Schlucht ist asphaltiert und gut begehbar (ca. 1,1 km lang) bis zu den Lower Falls, einem etwa zehn Meter hohen Wasserfall. Nach weiteren 2,7 Kilometern gelangt man zu den Upper Falls, die wesentlich beeindruckender aussehen und ca. 30 Meter hoch sind. Von dort führt ein steilerer, 5,8 Kilometer langer Weg zu den Ink Pots, kleine Seen die sehr schön in die Landschaft eingebettet sind und aus denen regelmäßig Blasen aufsteigen. Die Seen haben verschiedene Farben.

Johnston Creek originates north of Castle Mountain in a glacial valley southwest of Badger Pass and south of Pulsatilla Pass, at an elevation of 2,500 meters (8,200 ft). The creek flows southeast between Helena Ridge and the Sawback Range, and then south through a gorge known as Johnston Canyon. The stream empties into the Bow River, south of Castle Mountain, between Banff and Lake Louise, at an elevation of 1,440 meters (4,720 ft).
As Johnston Creek approaches the Bow River, it flows through a large canyon formed by erosion over thousands of years. The creek has cut through the limestone rock to form sheer canyon walls, as well as waterfalls, tunnels, and pools.
A popular hiking trail follows the canyon and leads to a meadow within the Johnston Valley above the canyon. The first part of the trail consists of a constructed walkway with safety rails and bridges, while the last part of the trail is natural and more rugged. Within the meadow are the Ink Pots, which are six blue-green spring-fed pools.
Ice climbing is a popular activity on the frozen waterfalls in winter.
