Customer notification when seller cancels order

[bbinfo]

I cannot find how to edit the email template of what is sent to the end customer when we, as the seller, cancel the order. I can see a record of the email sent to them in the transaction history but cannot find the template in the list of customer notifications in the settings window. Is this a standard Shopify template that cannot be edited, or is there somewhere else I can find it?
