We had assistance from a subway employee in choosing the T-Familiar card as the best option for us. That card gives two people a total of eight rides (or the equivalent of 16 single rides). Works out to $15 (Canadian). Before you insert the card into the turnstile scanner take note of which turnstile to use based on the direction of the LED arrow. With one exception it was always the turnstile (automated gate) in front of us. However, it was once the turnstile to the right of the card reader. On that occasion, by the time we received assistance we had wasted two trips. The trip is deducted from the card once the card passes through the scanner whether you use the turnstile or not. Overall, we found it easy to navigate the subway, including changing lines. It was fast and efficient. However, we weren't always sure which exit to take that would bring us closest to our destination but this only resulted in a bit more walking. We had no issues about potential pickpockets. On one occasion I was also offered a seat by a teenager. It probably helped that I am a senior with grey hair.
