Was a great year for Blue Jays. Enjoyed it. Just feeling a little down in mud today over missed chances. Oh well. Nothing like running into a cow on a sunny day for perspective

Noticed the low water levels on St Lawrence River today. This is predictable to some extent as part of Plan to replicate natural flows that existed before dam built in 1958 as part of seaway expansion. Enhance wetlands, fish habitat & shoreline health. ⁦‪@swimdrinkfish

Well that was a beautiful opening by Blue Jays tonight. Makes me proud to be Canadian, from Ontario, Toronto, Lake Ontario

The Lake Ontario powered Toronto Blue Jays are playing for the World Series. The fresh water, the Great Lakes & its vast watershed & the many nations who share the water everyday, make this a national, provincial & multinational fan base. Biinaagami.ca @swimdrinkfish

Such a disgrace. Govt’s have obligation to ensure our water is swimmable drinkable & fishable. It is the law. Shocking story hidden in plain sight. Feds 'covered up' toxic chemicals in the water in this Ontario city for 5 years | National Post nationalpost.com/feature/nort...
Feds 'covered up' toxic chemicals in the water in this Ontario city for 5 years
In 2012, DND found high levels of toxic substances in the water feeding North Bay's wells and municipal system. But residents didn't know.

Sometimes I think the Shagbark Hickory tree is the greatest tree on the River. Just looking at it gives you strength, much less hugging it, living under it. Time to plant more. #biinaagami @swimdrinkfish

No tariffs, no taxes, no entry fee — the Great Lakes waters keep working for Canada , US and First Nations as the foundation of economy, culture and health. To do harm to these waters is to do harm to ourselves. ⁦‪@swimdrinkfish‬⁩ @biinaagami
