I cannot see them calling the loan immediately. They can close it which means the credit facility is no longer available to draw on but regular payments are due. This would apply the same at any of the major banks. If you wanted to voluntarily close your line you could and still pay the minimum every month and be in good standing.
If they do not offer at the very least a scheduled amortization of atleast 5 years I would contact any of the following
