The policy goal underlying this was to ensure that individual provinces couldn't try to veto or extract undue benefit from projects that are determined to be in the national interest simply because a portion of the project is being built in that province. This applies equally to Coderre's ramblings about Energy East.

Except in a project like this there are still a whole host of things that provinces need to provide/are under their jurisdiction. For example a lot of wildlife restrictions are provincially controlled, building permits, etc.

If the province was withholding something based on something that was outside of their jurisdiction then yeah, it could definitely be unconstitutional, but there are a whole host of conditions the province could demand for a whole host of reasons that are well within their jurisdiction.
