London has become the latest Ontario city to approve a ban on shark fin products. City council voted 14-0 in favour of the move on Monday night. City staff will draft a bylaw to implement the ban. Experts estimate 75 to 100 million sharks are killed for their fins every year. The fins are used for such items as shark fin soup. Toronto, Mississauga, Oakville and Brantford have also approved similar bans.
