In December 2012, the Ontario Government launched the Health Links, a strategy to integrate care for patients with complex health and social care needs. The Health Links bring together multiple clinical and social service providers on a voluntary basis, including a minimum of 65% of primary care providers in each region. The Ministry of Health and Long-Term Care (MOHLTC)’s is utilizing a “low-rules” approach to the implementation of Health Links in an attempt to encourage organizations and professionals to determine how best to achieve system goals through experimentation and learning. The Ministry’s “low-rules” approach aligns with the growing application of complexity science principles, which argue that in complex systems effective innovations and improvements are more likely to emerge from the bottom up when the conditions are favourable.
