Hi Marywin,
I'm also from Toronto, and recently diagnozed with a large AN. I initially got referrals to Dr. Chen at Sunnybrook and Dr. Rutka at Toronto General. It took a few weeks to get the appointment after the referrals were sent, and got an appointment about a month after. I would keep calling to find out when your appointment is, you can call the ENT clinic directly if Dr. Chen's secretary isn't responding (I remember it was on the referral form, but i'm sure you can also find it online).
After seeing both doctors in Toronto, I also decided to see Dr. Akagami after reading the good reviews on this site. I emailed him directly, and his secretary responded to me that I need to get a referral from my family doctor, to be faxed along with all test results (I also ended up mailing a CD with my MRI, though I think they can request that from the hospital in Toronto). So you can just give your family doctor Dr. Akagami's details, and ask them to write you a referral. Just to let you know though, it took about 5 weeks to get an appointment notice after they received my referral (I just got it last week). I was also told it can take up to a year to see Dr. Akagami depending on the urgency. My AN is quite a bit larger than yours (about 3cm), and I got an appointment for the first week of May.
Hope that helps, good luck with your referrals!
Rumen
