Last I heard is that construction is at least a decade away.
The MTO doesn't recommend an interchange with Bradley as it is too close to the 401 junction. This would cause weaving.
-Have you ever driven on Highbury between Bradley and the 401? There's a third lane there on the right where cars have to merge on from Bradley and merge off to access Highway 401 westbound. That's a textbook example of weaving and it can be really dangerous.
See this video I made for the section I'm referring to. (It's between 0:30 and 0:34)

I think the City of London still wants a junction at VMP/Bradley but it will be a lot further back to minimize the weaving. A long half-cloverleaf might do the trick if the loop ramps are placed as far north as possible.
Hamilton Road will have a Parclo A-4 design. That's what's proposed for now.
Unfortunately I don't have any documents on my hard drive right now regarding these junctions. Try doing a search on the city website for documents related to the topic.
