Sorry, is that metres above sea level? So the Don River at Dundas is just 74.5m above the Atlantic Ocean?

Yes, elevations are metres above mean sea levelSorry, is that metres above sea level? So the Don River at Dundas is just 74.5m above the Atlantic Ocean?

Yup. Keep in mind that it's in a valley. The areas above the valley are 100m above sea level.

...it's less at high tide though.

The city of Toronto has a detailed map of the city on its website. Among many other things, there is a feature that shows elevation. At the top of the screen, go to the tab marked Basemap Gallery, and click City of Toronto Topographic. Then you can see any location's elevation to the metre.
Toronto's map also has things like property lines, park boundaries, and more recent satellite imagery than Google would show you. Most cities or counties have similar maps for public reference.

Generally, yes, it's metres above sea level, but more precise. That's why I quoted a "datum", i.e. a 'scale' based on a specific theoretical model of the earth.
I also made some assumptions, because TRCA didn't make it easy to look up what datum they use for their gauges. That's also why I want to caution anyone referring to the contours on the Toronto map, I don't know what datum that's in.
It's not a big deal talking about the concept of how high the lake is above the Atlantic, but it could make things way off on the scale of local lake and river fluctuations. I regularly work with two different datums (CGVD28 and CGVD2013) and they can differ between 30 and 50 centimeters around here.

If it was a trench, it no longer is as a result of sediment. If there is no rain in southern Ontario for a few days to a week, you can look over the Dundas Street Bridge and see the bottom clearly. You could literally wade across the Don River and it would not even go higher than your knees, when there is no significant rainfall for a couple of weeks. There was a homeless guy there, in a tent, for the longest time and he used to wade in the Don River in shorts. The water never even got close to his knees.
It's not just the straightening of the Don River that's the issue, it's how shallow it is as well. It does get much deeper the closer you get to the Keating Channel though.

This is a little morbid, but my friend who was a Toronto cop said when people used to jump off of the Bloor Viaduct some would land in the Don. He said one guy went in head first and was buried in mud with only his ankles visible in the water. Thankfully that doesn't happen anymore.

Trees have been fixed already but the no parking sign is still bent right over along the Don Roadway.
Don River Debris. See the purpose of these in action...
They are working on more planting and fixing up the land between the sidewalk and bike lane on the north side of Lake Shore Blvd East. Lots more soil going in.
Has society really come to this? Really? "Road Ahead". This really feels like someone is bored, getting paid way too much money and has to think of dumb ideas, or the city thinks citizens are idiots.
Maybe the logic is to aid blind cyclists who can't see the intersection clearly. <= if you don't see what I'm doing here, you are beyond help.

Perhaps the "Road Ahead" will be more useful as the vegetation grows & potentially obscures the intersection

But at least construction on the new Cherry Street Bridge is nearing completion!!
Love it when journalists are too lazy to find an image less than 3 years old.

The picture doesn't even seem relevant either. Why not a picture actually showing the Gardiner or DVP?

Fun fact, for Canada the Atlantic Ocean is about 30cm below sea level [Canadian Geodetic Vertical Datum of 2013].
