Maybe they have to wait until underground water is flowing freely to see where the leaks are in the stations and tunnels so they can fix them.I am scratching my head about what kind of work ought to wait until spring. Construction seems to mostly continue with winter temperatures, certainly concrete can continue to be poured with the right measures and protection. But frozen ground does change some things.

Frozen ground requires more effector and labour work, but can be done at a higher cost doing so.
Look at how they built the Finch guideway and trackwork where tents where built over it with heaters being used to keep things warm.
They are currently doing the heating on Mississauga guideway at Eglinton for the Hurontario LRT as well at a number of other locations with tarp over the areas.
