Oh, the public in Southern Ontario will be scared of that word that starts with "F", the Canadian nationalists will jump up and down like they do. Supposedly, we in Canada can never use the word "Freeway" but most always use the word "Highway". Just like it's called Grade 12 here and not 12th Grade. Or one that relates more, we call it Queen St W, not W Queen St. (Can someone seriously tell me why we throw the directions on streets at the end) I know that's the case at least in Southern Ontario, but not sure about everywhere.
Also, to what extent would you like to resurrect the M-C signage? The problem I see, is that with the overlap of the Highway of Heroes signage, especially with the MTO's obsession with bilingualism, can you imagine seeing a sign assembly in the GTA with possibly 5 shields? (Hwy 401, Highway of Heroes, Autoroute des Heros, M-C Freeway, Autoroute M-C) Or would you rather have the M-C designation appear like those big blue signs at the 404 and Hwy 35/Hwy 115 interchange (I think) every so often along the route. If I recall, it's like this in Quebec, where you see the periodical BGS that says "Autoroute Jean Lesage". Another example that I see once a year is the "Miners Memorial Highway" Big Blue Sign on Hwy 104 at least twice in Nova Scotia.
Speaking of multiple names for Ontario freeways, any GPS or mapping program seems to name the Hamilton section of Hwy 403 as Chedoke Parkway, was there any real acknowledgement to this name on the road ever? Same goes for the Conestoga Parkway, which I'm not sure what the K-W residents call that freeway that's sometimes Highway 7, or Highway 8, or Highway 85. I personally use the term "Conestoga Parkway" myself, but I'm not sure if anyone knows what that term means, I really only learned it from the mapping programs. I also recall Microsoft Streets and Trips, back in the early 20-aughts (and possibly still on MapPoint), had Hwy 409 have a second name known as "Belfield Expressway", is there any proof of this too?
Also, could we please get a proper cosigning in Wellington County, of Hwy 401 and Hwy 6, it irks me that the Hwy 6 sign on the assembly is a trailblazer, with a "TO Hwy 6", when technically you are on Hwy 6. I believe the one with Hwy 410, which doesn't exist since legally since '97 decommissioning, and the Hwy 401/Hwy 6, are the only cosignings on 400 series highways that cosign with regular highways. But I could be wrong. On a side note, check out what they've done to the Hwy 410/Hwy 7, sign on Williams Parkway...you'd be in for a laugh if you understand the funny error they made.
