The virtual signing ceremony saw the hereditary chiefs and government ministers witness each other signing the document through Zoom, as travel has been restricted due to the coronavirus pandemic.

The memorandum of understanding that's due to be signed will set the terms for months of negotiations on land rights and title for the Wet'suwet'en over their traditional territory in northern B.C.

The elected leadership say the pact on land rights and title has not been fully circulated to the Nation's clans for their input, and accuse the federal and B.C. governments of consulting in bad faith.

The hereditary chiefs oppose construction of a pipeline through their northwestern B.C. territories, while a majority of elected band councils support the Coastal GasLink project.

The agreement does not apply to the controversial Coastal GasLink pipeline project, which sparked the discussions that led to the deal.
