HMWN provides local Catholic programming for Toronto on weekdays into the evening hours along with the English language network feed of Radio Maria USA (originated by KJMJ 580 kHz in Alexandria, Louisiana) to provide the bulk of its overnight/early morning and weekend programming.
Upon its initial sign-on which took place on May 26, 2010 just days before the construction permit expiration date, WRMW initially aired separate pre-recorded programming from the network archives while it was awaiting the installation of its satellite receiver and dish antenna from originating station KJMJ 580 kHz in Alexandria, Louisiana.
According to a Springfield News-Sun story dated March 10, 2008, the station was purchased by Radio Maria, an Italian-based Catholic radio network which owns and operates KJMJ, its originating USA English-language station in Alexandria, Louisiana.
