Complaints are common. Cormorants kill trees. They eat too many fish. Their colonies stink.

Warren Hoselton has had enough. After three years of watching his beloved trees around his Ontario home be decimated by cormorant poop, he wants action. The birds have to go.

But not everyone has a hate-on for cormorants. Avian ecologists say it's not fair to fault birds for doing what nature designed them to do.

The ones living in a park on the edges of Canada’s largest city, reached 20,000 this year, angering locals worried about their impact. In Toronto, they’re trying to relocate them. Elsewhere, hunters shoot them.

All across North America cormorants make enemies because of the mess they leave behind.

It was supposed to keep Canada together but a massive 1995 rally nearly did the opposite.

In 1995, Canada was on the verge of breaking up. The province of Quebec was about to vote on whether to become a sovereign nation. Just days before a referendum on that very question, tens of thousands of Canadians from across the country poured into Montreal. Travelling by planes and trains - they gathered for what would become known as the Unity Rally. Carrying flags, singing the national anthem and declaring their love for Quebec – they pleaded for Quebecers to say “no” they would not leave.

Despite this demonstration – many in the Province viewed the gesture as too little too late.

30 years later Francis Plourde looks at the legacy of the love-in, and the historic vote and what it says about Canada today.
