Universal Market Integrity Rules
A set of rules governing trading on exchanges in Canada. All Canadian exchanges are required to adhere to UMIR, which, among other provisions, prohibit price manipulation and other practices deemed to be unfair. UMIR were written in part to create uniform practices throughout Canada so that a trader on one exchange would know and be able to abide by the rules on all other exchanges.
