In addition, the 401 serves 3 types of traffic: commuter, recreational and business (trucks... just in time inventory).
I would much rather have one monster freeway opposed to 3 or 4 crosstown expressways... as long as the monster freeway is efficient and well maintained.
The 401 could really benefit from some stacked interchanges (4-5 level diamond stacks, currently only 1 exists in Canada at 400/407) to keep traffic flow more efficient and a few additional lanes in the most bottlenecked and congested sections. Some HOV lanes could also help.

The worst bottlenecks are at 400/401, 427 to 409 (where it narrows to 10 lanes from 16, but since no ROW exists for any widening, a double-deck with express lanes over the collectors is the only feasible solution) and at the endpoints where the express lanes end. On the Mississauga side, expansion is planned. The ROW seems wide enough to extend the express-collector setup as far as Stevenson Road in Oshawa (just before entering the older part of that city) with minimal disruption, although some train tracks will need to be relocated.
Interchange upgrades could also be warranted at 400/401 (straighten and eliminate loop ramps plus add more ramp room), 403/410/401 (a 5th level ramp for 403 EB - 401 WB movements) and 404/DVP/401 (replace the loop ramps with 4th level ramps). HOV lanes should also be built along the entire 401 corridor, by converting 1 or 2 express lanes in each direction to such. Special HOV-only ramps should be built from the 401 to the other major freeways as well - namely the 407, 403/410, 427, 400 and 404/DVP.
Another thing with the 400: I think it should be extended downtown, roughly near the railway corridor. However, due to the minimal space available, it should only be built 4 lanes wide (2 in each direction), and should be RESTRICTED to HOV use (probably HOV-3 or HOV-4 in order to keep it moving). Commercial vehicles, except buses, would also be prohibited from it.
