Thanks for the detailed response Drum118 - helpful back information. I didn't realize there was a rule about not painting bridges.

I am not sure exactly what the requirements are, but painting is still allowed and done, on occassion.
For new bridges, Weathering steel is generally used. This is basically rust coloured, but it is a thin layer of surface rust (patina) which prevent further corrossion. This is cheaper than painting regular steel, but painting is still done if painting would better blend into the surroundings.
Older bridges were generally painted with lead based paints and repainting requires sandblasting in a negative pressure enclosure to capture all the sand and paint flakes for treatment before disposal (can't allow it to fall into river or atmosphere). If the existing paint is not peeling very much, it is possible to encapsulate the old lead paint with a new coating, which is a bit cheaper but generally does not last as long.
Construction start for Etobicoke North 2.0 is currently slated for January 2013.The traffic circle work on Resources Rd. and the additional construction work seen north of the rail corridor is not for a new Etobicoke North Station, but being done by Lowe's for a new store.
The new Etobicoke North Station lands are being clear on the east side of Islington Ave at 401, next to MOE.
Freight trains are not permitted under the shed unless they get the approvals from the highest officials at USRC / TTR. The circumstances that would trigger this would probably never happen.
North American loading gauges rule out platforms at carriage height without a significant gap where freight traffic isn't blocked.
