My personal initial response to your question is - no; this is really not an eating disorder.
I have had a look for organisations that may be able to assist you with IBS in Canada:
CANADIAN DIGESTIVE HEALTH
Disorders - Canadian Digestive Health Foundation
[Footnote: I do see they use the word disorder; but it is not used in reference to "eating disorder" at all - this is how I interpret this; I hope this helps]
