Feral Goldfish populations are increasing rapidly in Canada, with the average goldfish taking over local waterways and ecosystems. The increase in these populations is attributed to human release as the primary reason for their rapid growth, with provincial agencies describing it as a real ecological problem. The number of feral goldfish in Canada is increasing, with current Aquatic Invasive Species Regulations excluding goldfish from their rules, leading to delays in containment efforts across multiple provinces. Goldfish are now established in multiple provinces, particularly in urban and suburban ponds where they thrive. These fish are often released into ponds or connected waterways when owners no longer want them, causing them to thrive. Despite this, goldfish are known for adapting quickly to any new environment and are often adaptable to poor water quality and cold Canadian winters. They are also known for their adaptability to streams, pools, ditches, and ponds with submerged vegetation.
