Canadian routing numbers must be created from the financial institution's Magnetic Ink Character Recognition (MICR) code. For example, if a bank's MICR code is BBBBB-AAA, then its routing number in Forte's system would be 0AAABBBBB. The leading digit should always be zero. The three-digit code (AAA in our example) represents the financial institution, while the five-digit code (BBBBB) identifies the branch.
