Looking for Canadians involved in the first Earth Day

I've been researching the ways Canadians celebrated the first Earth Day back in 1970. Without any large governing body the event was marked by numerous, small-scale activities across the country. I've uncovered some interesting stories in interviews, newspapers, and at the archives, but I'd like more. So, if you (or somebody you know) were involved in activities associated with the first Earth Day here in Canada I would love to hear from you. Contact me at thegreatgreennorth@gmail.com.
