NEWMARKET - A shelter in Newmarket has cancelled an adoption blitz that was planned for Saturday after it received a stream of threats against staff.

The Ontario Society for the Prevention of Cruelty to Animals in York Region says threats were also made against members of the public for attempting to participate in the adoption of the animals.

The organization says the threats came from a small, but aggressive group of protesters.

The animals, which would have been available for adoption, have been transported to various sites across the province.

The shelter became the target of daily protests last month when it announced it was euthanizing animals to stem a ringworm outbreak.
