An Edmonton family is devastated by the sudden death of their dog. Daisy was rushed to the vet after swimming in Moose Lake, where AHS later posted a blue-green algae advisory.

While most commonly blue-green in colour, surface blooms can also look red, brown or yellow, and can produce potentially 'lethal' toxins, health officials say.

Canada will be up a creek without a paddle if it doesn't acknowledge threats to its fresh water, says a report from some of the country's top water scientists.

The dogs died just a few hours after swimming in a pond filled with blue-green algae, which can produce a powerful toxin.

A Whitby, Ont., family believes blue-green algae in the water may be to blame for the dog's death.

According to the health unit, some varieties of blue-green algae are capable of producing toxins that can be harmful to humans and animals.

A recently published study suggests climate change may encourage longer and more frequent blooms of toxic algae along Canada's Pacific coast.

A vast bloom of toxic algae off the West Coast is denser, more widespread and deeper than scientists feared even weeks ago.
