Huh - didn't know about that one. Here it is in 1989:
View attachment 422383
Looks like it was signalized only in the southbound direction. At the time, the 427 ended at Indian Line still, but 1992 imagery has the 427 extended north to Highway 7, with the signal still there. Pretty crazy to see a signal on a 6-lane freeway! I imagine the Morningstar overpass was constructed in conjunction with the 407, but Toronto has a gap of online air images from 1992 to 2005 so it's hard to tell.
Thekingshighway.ca states that the SB 427 lights at Morningstar were removed in 1996. And I distinctly remember that intersection from my teenage years.
