This stunning @globeandmail photo essay documenting the restoration of the Don River mouth tells us something profound about who we are as a city: 1. Citizen activism matters. The citizen-led Task Force to Bring Back the Don worked tirelessly for over 30 years to keep the vision alive, hold politicians accountable, and demand the highest standards of environmental stewardship. 2. We’re capable of doing extraordinary things when we take the long view and commit to the hard work. This area was once a contaminated, degraded landscape. Decades of studies imagined the path forward, but as these images show, there was no substitute for patient, hands-on restoration. 3. This is the kind of work that calls on the best in us. Projects like this don’t happen without deep collaboration, technical excellence, and long-term commitment across many disciplines. They challenge us to rise to the occasion and to contribute our skills toward something lasting, something bigger than ourselves. Few undertakings are more worthy of our highest efforts. As PM Carney launches a next generation of infrastructure projects, I hope this serves as proof that when we aim high and stay the course, we can build cities and a country worthy of the next generation. theglobeandmail.com/opinion/…
