Anderson’s in Burlington is a very respected dealer. The owner is also extremely pleasant to talk to on the phone. Another excellent dealer is in Victoria, Martin at Tempo Music. Don’t worry about he being almost across the world,Martin ships everywhere around the world and you can’t imagine a kinder,more enthusiastic dealer than Martin. He has several videos online where he talks about picking out an accordion. I have spoken with him several times and I know someone who uses him all the time,he is incredibly honest and friendly.
Long and mcquade is useless for accordions. I live up the street.they don’t sell used accordions which is all a beginner needs.
I have known the only accordion teacher in Toronto for more than ten years. Like Martin she is very supportive of all of her students. She teaches at a school near queen street. But because of covid she has taken the year off. Both Martin and this teacher are the best people for students of the accordion. Highly professional and very supportive of new students.
I mention this every time a site like eBay comes up. My first accordion was from eBay and the buttons started popping out. The second time I bought online,I wanted a free bass,an even bigger disaster. The bellows didn’t work,never again. Any honest dealer will allow you to return the instrument if you aren’t happy and no reputable dealer will see you garbage.
