In late 2015, as Europe grappled with a migration crisis of a scale not seen since the Second World War, the United Nations decided to convene a meeting to address how member nations can respond.
A year later, 193 member countries signed on to the New York Declaration, which called for the adoption of a migration pact by the end of 2018.
As a result, the Global Compact for Safe, Orderly and Regular Migration was born. A draft of the pact was agreed upon by UN members — except for the United States — in July.
On Dec. 10 and 11, United Nations members will gather in the Moroccan city of Marrakesh to formally adopt the pact.
Canada is expected to sign on, but several countries have expressed reservations.
