Hello:

I am asking this question on behalf of a family member who sadly suffers from Type 1 diabetes. This means that he has to carry insulin and a bunch of other gear (all of which must be stored at mild temperatures) . He will fly Z class and carry 1 personal item+1 carry-on roller luggage. I have no experience in a Bombardier CS300 and therefore am asking about their overhead bin space. Key question: will he be forced to gate-check his roller luggage? I heard that many Canadian jets are very small.

Thanks in advance.
