Montreal's Defence Lawyers Association is planning to meet later this week to discuss the safety of its members, following the attack on criminal lawyer Gille Doré.
Doré, 58, is known for representing alleged Hells Angels. He was badly beaten outside his home in Montreal's Outremont neighbourhood on Friday evening.
Police would not confirm the victim's identity, but did say they have no suspects in the beating.
Richard Prihoda, the head of Montreal's Association of Defence Lawyers, said his members are in shock.
Doré currently represents several presumed Hells bikers arrested two years ago in Operation SharQC, a massive dragnet against organized crime.
He rose to prominence a decade ago while defending high-ranking Hells members in Quebec's notorious 2002 mega-trial that ended with the murder conviction of Maurice "Mom" Boucher.
Prihoda said it's not clear the attack against Doré is related to his work, but he acknowledged that large mega-trials are "very demanding."
There has been at least one other violent attack against a Montreal defence lawyer in the past 11 months.
Last December, Joseph La Leggia, another lawyer working on the SharQC case, was attacked in front of his home in Rivière des Prairies. Police have not made an arrest in the case.
Another Outremont lawyer, Thomas Kiriazis, was the victim of threats and intimidation last month.
Prihoda said he hopes police solve the two assault cases soon to deter further attacks against defence lawyers.
