Halton Regional Police have charged the man driving the truck that struck and killed an animal rights protester.

The 28-year-old man from North Perth has been charged with the Highway Traffic Act offence of careless driving causing death in the June 19 incident that left 65-year-old Regan Russell, of Hamilton, dead.

Halton police aren't releasing the man's name as the charge isn't criminal.

"There were no grounds to indicate this was an intentional act, or that a criminal offence had been committed," Supt. Kevin Maher said in a release.

He added: "This investigation included the interview of several witnesses, analysis of physical evidence, and a technical reconstruction of the collision. In addition, video footage that captured the entirety of the incident was reviewed by investigators."

Russell was struck by a transport truck that was hauling pigs through the gates of Fearmans Pork meat processing facility at Appleby Line and Harvester Road at around 10:20 a.m. on Friday, June 19.

The truck with its cargo of squealing pigs remained at the scene for several hours as police blocked off the area and began their investigation.

Witnesses said Russell was struck while giving water to the pigs in the truck, but Halton police have neither confirmed nor denied those accounts.

Her sudden and violent death sparked protests by animal rights activists demanding action against the truck driver and improving laws to protect such protests.

A large animal rights group today says it is condemning Halton Regional Police after what it calls a "feeble" charge against the truck driver in the death.

“These charges are feeble and do not amount to justice for Regan. Enough is enough," said Anita Krajnc, co-founder of Animal Save Movement.

Krajnc, also co-founder of the group Toronto Pig Save, said Russell was a respected and revered animal rights activist.

“What happened to this activist is beyond tragic. She was a beautiful, beautiful woman who was kind and compassionate, loved animals, wanted the world to go vegan,” said Krajnc. “She has been doing animal activism for years. She just spoke her mind, she was very articulate. She was a beautiful woman and I can’t believe she is dead. She’s an angel and she was giving thirsty pigs water.”

Fellow protester and Russell's friend, Kelly Simpson, said there has been and continues to be "outrage" over what happened and activists are still angry because criminal charges weren't laid in the case.

Russell's partner Mark Powell said: "We can’t let the cause she was fighting for become lost in a fog of outrage."
