Anthony Leek, Randy Nickle and Tim McKillop are healthy candidates.
They're among more than 100 candidates in the provincial election pledging to the Heart and Stroke Foundation their parties will invest more to promote and support better health in Ontario.
The Foundation's campaign in 2011 attracted 86 per cent of the elected MPP's.
The Green's John Northey in Thunder Bay-Atikokan is the only other northwestern Ontario candidate to have signed the pledge.
