I’ve been reading a lot about the LA river recently because of the announcement that Frank Gehry is working with the City of Los Angeles on plans to revitalize the river (plans that some say may clash with previous plans to renaturalize part of it.) So I decided to check out one of Toronto’s own mini-LA rivers, Black Creek.
My first glimpse of Black Creek was before I knew it was Black Creek. I saw it as I passed by on the new UP Express on my way to Newfoundland for a friend’s wedding last month. There, outside the window of the train, I saw a large concrete channel marching down the centre of a street, a trickle of water down its middle. What is that, I thought. It looked so un-Toronto to me.
Turns out it’s part of Black Creek, one of Toronto’s most polluted waterways and the smallest subwatershed of the Humber River, into which it flows.
According to this little history on the Black Creek Conservation Project website, Black Creek was channelized following Hurricane Hazel in 1954 as a way to prevent flooding and whisk stormwater away faster. It was apparently fully surrounded in its open concrete channel by 1965. The effect is pretty dramatic. It’s horrific and beautiful at the same time, in the way that weird, concrete urban things often are where nature has started to reinsert itself in all the little nooks and crannies.
Not all of the creek is this austere, however. What makes Black Creek so interesting is how its concrete channel passes through different landscapes. Following the section where it slices down the centre of a road, the creek passes through a series of parkland before it runs through a golf course and then meets up with the Humber River.
Here the creek’s concrete channel winds its way through mowed grass, willow trees with their boughs hanging low over the water, and alongside tennis courts, children’s playgrounds, and ponds with green water so still that their surfaces appear solid. In some places rocks have been placed in the channel to break up the water, creating more of a natural look. Geese hang around on the concrete like bored teenagers.
While signs warn people about the potential dangers of flooding during rainstorms, there is no fence to keep you from going down into the channel. The banks are sloped gently and the base of the channel is flat and wide on either side of a trench cut down further where the water flows past. It’s almost like two sidewalks.
There are other creeks in Toronto that have been corralled into concrete channels like this one. Shawn Micallef has written about two others, Lavender Creek and Mimico Creek, both of which have been at least partly channelized.
These concrete streams are a weird mix of nature and the hardest parts of urbanity. LA’s plans are to get rid of the concrete for the LA River and soften the banks in the hopes that this restores some of the natural elements to the river itself. But Gehry, perhaps not surprisingly given his architecture, is interested in preserving the concrete portions of the river, calling it an “architectural feature.”
All environmental concerns aside, I can kind of see his point. Concrete is ugly and brutish, but that’s part of its appeal, especially in contrast to the soft, green of the parkland around it. There is something weirdly lovely in an almost dystopian sense about seeing Black Creek wind its way through the city in its concrete chute on its way to the Humber.

Worse is the turning Garrison Creek, Taddle Creek, and others into sewers. At least Black Creek is open to the sky, instead of being completely surrounded. See http://www.lostrivers.ca/content/centralkey.html
W.K. I disagree re: Garrisson Creek and Taddle Creek. Converting them to sewers was eminently sensible giving the situation the city was facing at the time. The urban neighbourhoods around them were densifying quickly, and the creeks were literal pools of disease, which flooded every spring and after every major rainfall in the summer spreading plague and pestilence with them… to poor people who lived nearby and didn’t have the choice but to do so.
What alternative would you have provided at the time?
The Highland Creek is also heavily “channelized” in certain areas. Black Creek, Highland Creek, and pretty much every other creek and river in the city has been fully covered photographically on this site: http://urbantoronto.ca/forum/threads/urban-wilderness.17775/
