Following up... I don't know Canadian copyright / trademark law, but I don't see how they can possibly fine you anything since you have not released the map. Reproducing something that exists physically in 3D and releasing a video of it is by no means a violation of copyright. You are certainly not making money off of a YouTube video showcasing work in progress. The metro is not being damaged by your video.
Again, I would seriously thumb my nose at those morons and remove the logos, change around some of the lighting and layout, and release the map calling it "Le Subway"
This was the fallback plan if GE:S ever received a cease and desist. We would remove all offending copyright and trademarks and release the game as a generic spy game. We have never made a single penny off of this game, not even with advertisements, so we could all say in very good faith that we are in fact in debt due to our work.
