The hydro corridors in Toronto are primarily lower voltage lines for delivery into neighbourhoods. The major 500 kV lines leading into the GTA come from the west (Nanticoke and Bruce) into a major transformer station in Milton, from the north (Sudbury) into a major station in Vaughan, and from the east into a major station in Pickering. 500 kV lines connect those three stations along the 407 corridor.

For a short time it was actually the largest after the one in Japan which was the largest for the longest time was shutdown following the Fukushima disaster. I believe the largest is now in Korea, though.

There are two major interconnects (Outaouais and Beauharnois near Cornwall) between Quebec and Ontario, and a bunch more minor ones. Outaouais is is unique in that it is an HVDC intertie directly between the grids, while the others are simply power stations on the border that have the capability to have some capacity directly connected to either grid. The total capacity between them is only 2 GW, or so, and is mostly limited to supply the Ottawa area and Eastern Ontario.
