Canadian cities, like many cities all over the world, have a historical past of hiding waterways underground. As cities develop rivers can turn into obstacles to the motion of individuals, will be seen as wasted real-estate, and traditionally (when cities had poor sanitation) they usually grew to become open sewers. For these causes cities usually culvert and divert rivers underground.

In Uncover The place Historical Rivers Stream CBC has mapped out the hidden subterranean waterways of Toronto, Montreal and Vancouver. These maps are used to take the reader on a tour of every metropolis’s underground rivers. These story-map excursions are full of some great transitions between the map and  overhead drone captured imagery. For instance within the screenshot above CBC seamlessly transitions between the map and an overhead video of a multi-lane freeway.

There’s a rising motion in lots of cities all over the world to “daylight” city rivers, to return them to the floor. This could enhance water high quality, create leisure areas, and reconnect folks with nature within the metropolis. CBC explores the argument that resurfacing city waterways may help cities take care of “warmth islands, flooding, air pollution, and (the) lack of ecosystem variety”.
