Canadian Prime Minister Justin Trudeau said on Sunday that Canadian military intervention in Haiti cannot happen unless it is approved by all political parties in the troubled country.

Trudeau spoke from Tunisia where leaders at the annual Francophonie summit held meetings about Haiti on the last day of their two-day gathering.

Trudeau also announced $16.5 million to help stabilize Haiti, where gangs are choking off access to fuel and vital supplies amid a worsening cholera outbreak. About half of the funds are directed towards humanitarian aid, and some of the rest aims to help eliminate corruption and prosecute gender-based violence.

But the Haitian government has requested international military intervention to fight the gangs that are choking off access to fuel and vital supplies amid the outbreak. The United States said Canada would be an ideal leader for such a military intervention.

Also, Trudeau said on Sunday that Canada is working with CARICOM, the Caribbean Community of Governments, along with “various actors in Haiti from all different political parties” to reach a consensus on how the international community can help.

Trudeau said in French: “Canada is very open to playing an important role, but we must have consensus from Haiti.”

The Canadian Global Affairs assessment team sent to Haiti to gather some understanding of what is happening and what can help has already returned and presented a report at meetings that Trudeau said he attended. He added that the need for consensus comes from a “very difficult” political dynamic in Haiti.

In the same context, Canada extended its sanctions on the political elites on Saturday by adding three more names to the list of Haitians whose Canadian assets will be frozen. Foreign Minister Mélanie Joly said the sanctions target those benefiting from the violence in Haiti. Joly also called on other international partners to follow suit.
