There is no room to expand beyond the 416 (barring massive expropriation) though. Looking at traffic counts, it should be 8 lanes through most of the city (which it already is for the most part), so the biggest traffic deficiencies are not in the core area. Yes, it can be congested, but it is mostly at the choke points, not chronically congested through the city like it is on the hill to Eagleson. Not until traffic counts get to about 200,000 will it likely require further widening, and with transit improvements, that will not happen for a long time most likely.
I believe the ultimate plan is for 8 lanes to Palladium Drive, and 6 lanes to Highway 7. The traffic counts (extrapolated to 2009 estimates) along Highway 417 are once east of the following points:
West March Road - 27,000 (supports 4 lanes)
Highway 7 - 43,000 (supports 6 lanes)
Carp Road - 48,000 (6)
Palladium Drive - 56,000 (6)
Terry Fox Drive - 69,000 (6)
Eagleson Road - 103,000 (8)
Moodie Drive - 109,000 (8)
Richmond Road - 128,000 (8)
Pinecrest Road - 141,000 (8)
Woodroffe Avenue - 148,000 (8)
Maitland Avenue - 152,000 (8)
Carling Avenue - 159,000 (8)
Parkdale Avenue - 169,000 (8)
Bronson Avenue - 154,000 (8)
Kent/Metcalfe Streets - 138,000 (8)
Nicholas Street - 158,000 (8)
Riverside Drive - 154,000 (8)
St. Laurent Boulevard - 134,000 (8)
417/174 split - 83,000 (6)
Innes Road - 66,000 (6)
Walkley Road - 40,000 (4, to 6 by 2012)
Anderson Road - 35,000 (4, to 6 by 2020)
Boundary Road - 28,000 (4)
