The annual Northwestern Ontario Municipal Association convention is on in Marathon starting Thursday. The organization acts as a voice for area municipalities at Queens Park. Mayor Lynn Peterson says this year local lawmakers will be dealing with about 20 issues. She says the resolutions include the number of federal seats in northern Ontario and moving the Northern Growth Plan forward. She says it's also an opportunity for municipal leaders to discuss regional issues with the provincial cabinet ministers who'll be attending on Friday. The conference runs until Saturday.
