Teva Canada Ltd. v. Bank of Montreal, 2016 ONCA 94, contains everything you ever wanted to know about how cheques work and is a case study in financial risk. This is interesting reading for anyone who works with cheque systems or is seeking to replace them (re: Fintech industry). The litigation is focussed on the (federal) Bills of Exchange Act.
The case began with a Teva employee writing cheques to himself for around $5 million. The employee registered Master Business Licenses (MBLs) for names similar to Teva customers (and then a couple imaginary ones).
