Four days ago I transferred in Toronto on my way to Edmonton and that experience far exceeded today's misadventure in Montreal on my way back to Connecticut.
Toronto had excellent and very easy to read signage. Montreal's was lacking... to say the least.
Toronto had dozens of friendly guides and service agents, seemingly every fifty feet to help and answer questions. Montreal had zippo.
Somehow, I missed the left turn to bring me to security and customs when luckily I saw a young guy driving in the terminal on one of those carts. I asked him where Gate 89 was and he said I was way off. He took pity on me and drove me through what seemed like half the terminal and dropped me off with instructions to just follow the purple signs.
I gave him my best "Merci Beaucoup" and walked through the security gate into the checkpoint (shoes off, belt off, laptop out) and then to Customs for my exit interview.
Had I not run into that young gent on the cart I'd still be wandering around.
At least the free WiFi worked great.
