Mr. Payday is essentially a brand of Focus Financial, like Uncle Payday. They do maintain separate lending licenses and physical addresses however. They operate legally in British Columbia, Alberta and Ontario, but appear to offer loans in all other provinces, albeit not legally as they do not appear hold payday lender licenses anywhere else.
In 2018 they were subject to an enforcement action by Consumer Protection BC. More details at https://www.consumerprotectionbc.ca/recent-enforcement-actions-details/?cpbc_document_get=&cpbc_document_api=/api/Complaint/Document/&cpbc_document_id=560
