nada is a Canadian company based in nearby Dundas that sells sustainable, eco-friendly toothbrushes shown to be better for the environment than electric, disposable and even bamboo toothbrushes (reference). Their sleek design includes an aluminum handle (that you keep for life) with detachable brush heads. You can ship all used brush heads back to nada, where they will be recycled into plastic pellets for use in new products. Locally made here in Ontario.
