You are trolling the upper forums.
Am I supposed to let you know, here in the upper forums, that the ENTIRE geological structure is way above sea level?
We are measuring everything with respect to LAKE ONTARIO LEVEL, not sea level.
Sure, the Niagara Escarpment is located at a higher elevation than Lake Ontario:

However, then I will bring here all over again the multitude of photographs taken in Grimsby (45 to 170 meters altitude) which exhibit no 59 meter curvature of water.
The question is, why on a flat earth is Toronto submerged under dozens of meters of water?You are dreaming.
On a FE Toronto CANNOT be under any water, on the contrary.
The following photograph demolishes RE.
It can only have been taken on a flat earth.
Data for St. Catharines, Lake Ontario, distance to Toronto, 50 km:
2 meters (observer) - 158 meters (visual obstacle)
3 - 150.5

These are the facts concering the photograph from St. Catherines.
Even with 3 meters, you still have to deal with a visual obstacle of 150.5 meters.
86 meters + 9 meters (courtesy of the FES) = 95 meters for the Sky Dome
150.5 - 95 = 55.5 meters to be accounted for.
Good luck.
Now, please explain to your readers, and for that matter to yourself, HOW THE WATER LEVEL OF LAKE ONTARIO STAYS CURVED ON A ROUND EARTH.
You can't use either attractive gravity or general relativity.
By pure magic, isn't it?
This is exactly what you are telling everyone here is happening: on a spherical Earth the water level stays curved by pure magic, nothing else.
