Is Diabetes a Problem to Canada Immigration?

Whether diabetes makes an applicant medically prohibited to Canada?
As with many medical issues, the reply is "it depends"

Diabetes is not, in general, a bar to migration if there is no nerve end damage and it can be controlled with diet, medication or insulin.

Though, an assessment is always based on individual circumstances and a medical exam. Please get officially authorized advice and a medical view before deciding if your diabetes will prevent you from immigrating to Canada.
