After three years in hibernation, WWF-Canada's CN Tower Climb for Nature is back! We're celebrating 31 years of coming together to reach remarkable heights for nature and wildlife. With climate change impacts increasing and a million species worldwide at risk of extinction, climbing the CN Tower is a rare and exhilarating opportunity to help WWF-Canada reverse the course our planet is on by taking 1,776 meaningful steps towards a brighter future where nature and wildlife thrive.
