The Toronto G20 summit in 2010, had a security budget of over a billion dollars, resulting in the largest mass arrest (1118 people) in Canadian history. In 2020 Toronto police said they ‘regret mistakes were made’ in mass arrests and reached a settlement of $16.5 million brought by the unlawful arrest class-action lawsuit.
Notoriously the police kettled around 300 peaceful protestors and by-standers and held them for 4 hours in the pouring rain at Queen/Spadina. To date Supt. David (Mark) Fenton only senior police officer held accountable for the massive breach of civil rights that occurred and will lose 60 paid vacation days.
