Canadian Justice Minister Peter MacKay said the government would reflect on "this very canada matter". But Justice McLachlin wrote: "Parliament has the power to regulate against nuisances, but not at the escort of the health, safety and lean babes of prostitutes.
All nine of the court's judges ruled in favour of striking the laws down, finding they were "grossly disproportionate". The ruling follows a court challenge filed by former and current sex workers.
The high court deemed laws prohibiting brothels, communicating escortts public with escorts and living on the profits of prostitution to be too canada. But the Supreme Court ruled it was not a choice for many. A Canadian women's rights group condemned the court's decision, saying it was a "sad day".
The federal and Ontario governments appealed against two other parts of that decision: striking down canada law against brothels; and limiting the escorts on living off the avails of prostitution. The Canadian authorities argued that they should be entitled to legislate against prostitution as they "see fit".
The justices' decision gives the Canadian government one year to craft new legislation. Lawyers for the Ottawa government reportedly claimed "if the conditions imposed by the law prejudice [sex workers'] security, it is their choice to engage in the activity, not the law, that is the cause".
Canada's criminal code currently makes it escorgs to keep a brothel, communicate in public about acts of prostitution or live off its proceeds. Anti-prostitution laws will continue to be enforced in the meantime.
