Here are 4 television ads from Subway Canada I worked on.
My job was to design the backgrounds. Some sets have been adapted to 3D afterward.
The commercials were broadcasted during 2013 and early 2014.

The whole campaign introduces "The Super Morning Squad" (the monkey mascot and "the ingredients" as super-heroes). They come to save the day!

Video 2: Super City
Video 3: Temptation Road
Video 4: Breakfast Fiery
Here are some backgrounds that were used in the first commercial:
