UPDATE: The Ministry of the Environment has found no traces of blue-green algal bloom along the Ryerson Park waterfront.
Officials took samples from three different locations in the area last Wednesday.
The town is still warning people to be cautious around the waterfront.
Water testing is not conducted regularly in the area because it is not a designated beach.
Several factors can promote the growth of bacteria in the water including excessive heat, strong winds, recent heavy rain and lots of swimmers.
A dog has died after visiting the Ryerson Park waterfront in Niagara-on-the-Lake.
The Upper Canada Animal Hospital is calling it a classic case of toxic cyanobacteria even though the official cause of death has not been determined.
Toxic cyanobacteria can be fatal for animals and humans if its ingested.
The town has notified the the Ministry of the Environment and Niagara Region Public Health.
The area was tested for Harmful Algal Bloom yesterday and people are being asked to stay away until the results come back.
Signs have been posted in the area and officials are also monitoring other waterfront areas in Niagara-on-the-Lake.
