Is there a limit on height for a male model?

Just wondering if there is a height limit for male models. I currently stand at 6'4 and I am afraid this may be my achilles heal. I was approached by a lady who worked in the fashion industry her entire life and she told me to move to montreal right away and become a model, she claims that I am exactly what they are looking for. She is also from montreal. My fear is thhat I may be too tall? Can my height be a problem?
