When did the man leave Canada?

Listen to the conversation, mark each question as A, B, C or D according to your listening.
W: How long have you been away from Canada?
M: We’ve only been in Madrid for four months, but I’ve lived abroad for a long time. Since I was twelve I’ve lived in three different countries: Russia, Greece and now Spain.
W: That means you’ve been to lots of different schools. Has that been difficult?
M: Well, I’ve been at international schools which give lessons in English. But yes, it’s difficult when you start at a new school in a foreign country. You don’t know anyone and you feel a bit lost. The first time was the worst-—that was in Russia. I was really confused and lonely for a while. And then, when I started to feel at home, Dad got a new job and we moved again!
W: So what’s it like now in Madrid?
M: I think I’ve adapted quite well and I’ve started to learn Spanish. Of course I’m still a foreigner, but I don’t mind that any more.
W: Have you enjoyed moving from place to place?
M: Yes and no. It’s always interesting and it gives you confidence. But it’s hard when you have to leave and say goodbye.
W: Do you ever go back to Canada?
M: Yes. In fact I went back to my old school in Toronto for six months last year. In some ways that was the strangest experience I’ve ever had. Everything was the same, but I was different! I felt a lot older than other kids of my age.
W: Is Canada still "home" to you?
M: Of course. I do really miss it, but it would be quite hard to live there all the time.
