There is something very important I have to say at this time. After spending only 2 whole days in London, England, I've realized that the underground subway system in Toronto, Canada is absolutely garbage.
Toronto = barely 4 proper lines. London = 13 lines.
Toronto population = 2,503,281. London population = 7,172,000.
Maybe that's why? But honestly, we can use more subway lines than what we have. We can learn something from the English. As long as it's not how to smoke 100 cigarettes a day.
