Wellesley Rekai Centre for Long-Term Care
The 9,750 square foot green roof at Wellesley Central Place illustrates the evolving sophistication of the long-term care sector, while providing an eco-friendly environment that benefits the community at large.

The pre-cultivated sedum-moss blankets were installed in 2004 directly on top of the washed river stones on the inverted roofing system.

The philosophy behind providing a green roof here is that long-term care is not just about health from a micro perspective, but that on a macro level a green roof provides environmental and community benefits.

The Wellesley Central Place allows for free public green roof tours conducted through Xero Flor Canada.

The City currently has green roofs built on three City-owned buildings, with seven more planned including one on the City Hall podium. There are six built ABC-owned buildings with seven more green roofs planned.
