Premier Greg Selinger made the promise in his health minister's riding -- a hard-fought Winnipeg seat.
Selinger says three of the new clinics would be a one-stop shop with doctors, nurses, pharmacists and social workers.
Three other clinics would be run by nurse practitioners who could treat routine health problems such as sore throats.
Selinger says the clinics would cost $21 million and would make community health care more accessible.
Manitoba voters go to the polls Oct. 4.
