The
EA table from the city's website says that an EA is about to launch for the widening of Oxford Street West between Sanatorium Road and Westdel Bourne.
Will post more material here as it becomes available, but the main reason I made this thread now is because a couple of days ago, the city posted the complete EA package for the Oxford Street and Gideon Drive intersection improvements, which recommends a roundabout. It's in the public review period until July 23rd:

It's also worth noting that Middlesex County recently completed their own EA that recommends the widening of CR14 Glendon Drive (which connects to Oxford Street West at city limits). Though I can't remember exactly if their widening will go all the way to city limits.
On the topic of Glendon, a roundabout will also be constructed in Kilworth at Glendon and Vanneck next year.
Here are the PIC slides for that from May.
