Trains have already been procured and are being built. So, no. Unless Brampton wants to buy a whole fleet of new trains.

Are the LRT tracks running on a separate ROW across the 407?

^ I think the bridge is being widened. Update: from the June 2017 drawings from the Metrolinx's Hurontario LRT page.

Drum mentioned the 407 piers are for the new 407 on ramp. I guess with the on-ramp moved off the main bridge, the middle lane gets freed up for transit down the centre.

^ Yes looks like it. The drawing I posted above doesn't show the existing layer.

407 bridge that will have a guide-way for the LRT

Just for complete clarity for @Transportfan 's question, the guideway will be in the centre, correct? So the construction in the 407 median is to widen the bridge for the car lanes/ramp lanes, right? I didn't have a chance to measure the existing bridge width and compare it to the drawing posted above.

Also depends upon what the actual width of the traffic lanes they will use. Currently, arterial road traffic lanes are not designed for the posted speed limit, but for the "safety" of speeders doing twice the posted speed limit (or more).
From link. Mississauga used 3.5m as a "standard" width and 3.75m for trucks. (Maximum truck wide is 2.6m for refrigerator trucks, see link.)

Standing in the middle of the existing bridge, it not wide enough to support an LRT in the middle. Only when I looked over the side of the bridge at the work on the barrier did I see the pier support that very close to the bridge. It was then I said to myself that they were planning to built a new off ramp so the LRT can be built on the bridge. Even the 403 will not support an LRT and why a new bridge is being built for it.
The 401 bridge was rebuilt with provision for an LRT in the middle.
Reading the drawing, it is showing that the bridge needs to be widen with the yellow and purple markings.
The current speed limit on the road will be a lot lower than it is today in the next 5 years.

^ I think the purple lines are the property lines.

This latest picture gives a helpful perspective on the widening.

And more pictures here. The top two pictures on the preview below appear to show new pillars being added under the existing bridge. Interesting.

As part of the Hurontario LRT project, work has advanced to widen the underpass at Highway 407 to create a new centre and independent deck to carry the LRT guideway. To ensure the underpass can support this weight, crews are driving prefabricated piles into the ground to add further support to the structure.

Interesting, I'd have thought that LRT has a lower per axle weight than a transport truck, though I suppose the fact that it's longer (having more axles than a truck, plus future coupled pairs) increases the overall load on the span. Does anyone know if they're planning for embedded track here or if they'll use ballasted like ION did for Northfield Dr over highway 85? My assumption is that ballasted track adds less weight to the bridge than embedded.

Im pretty sure they're doing ballast track on the whole line due to budget cuts from the province
