General Road and Highway Discussion

This expansion will be, for the next 10 years, a godsend to Mississauga.
It will be more than enough capacity to get through Mississauga at rush hour.

However, for those continuing through in the morning (inbound) commute, it will mean that cars get to the backup at the 427 sooner.  That backup, on the 401 next to Pearson, will become noticeably larger.  Anyone whose commute uses that section of the 401 but not the widened part, will see more, slower traffic than before, since the 401 will be able to pipe more in to the existing bottlenecks.

I'd argue that the 6-lane section through Mississauga is actually the larger and more severe bottleneck. That section (between Mavis and Mississauga Road) is regularly backed up well after the rest of the GTA highways are moving well again, even as late as 11am sometimes.
