As discussions got underway Tuesday, a number chiefs raised concerns that consultations on the framework promised by Trudeau have been lacking and that legislation on rights and Indigenous languages are being rushed in order to see them passed before the 2019 election.

Others expressed distrust of the federal government, dismissing Trudeau's frequent promises of a new nation-to-nation approach as little more than empty platitudes. Trudeau himself is scheduled to speak to the assembly Wednesday.

Carolyn Bennett, minister of Crown-Indigenous relations, insisted Tuesday that no final decisions have been made on the rights recognition and implementation framework, which she said has yet to be even written.

"We know that the process isn't perfect and we welcome any advice. We want your communities to know that and we want to continue to improve how we engage," Bennett told the delegates.

"The era of Ottawa determining how and when and where your rights are implemented is over, and you need to hear from me directly: nothing will be imposed."

Bennett said she recognizes the government needs to get out of the affairs of Indigenous nations and "disentangle from the colonial practices of the Indian Act."

"We're still working hard to prove that we are in no way on any 'white paper' path. We are determined to work with you on a path to vibrant, proud Indigenous nations that are in charge of their lives and their land. This is the opposite of assimilation."

Conservative Leader Andrew Scheer took the podium later in the day, striking a conciliatory tone — "open hearts and open minds," he said — and taking pains to accuse Trudeau's Liberals of being all talk, no action on Indigenous issues.

"Building that trust and mutual respect comes from listening to the Indigenous people of Canada, comes from opening a dialogue and that's what I'm here to do today," Scheer said.

"As a country we must do more than just speak words. It's time for us to work together and achieve meaningful and measurable results."

NDP Leader Jagmeet Singh highlighted his party's long-standing commitment to forwarding and promoting Indigenous issues.

He, too, took aim at Trudeau's Indigenous rhetoric, saying consultations on substantive legislative changes have not respected the notion of "free prior and informed consent."

"A truly nation-to-nation relationship and consultation doesn't mean symbolic or paternalistic consultation,"he said. "It doesn't mean you consult when government has already decided the results of the process."

Chiefs and delegates raised their own concerns about the progress of government's framework and questioned how they are being respected as sovereign nations if their rights are being enshrined in legislation over which they have no direct control.

A detailed resolution calling on government to comprehensively engage with and consult First Nations on the framework was met with so many amendments and concerns from the floor it was tabled for later discussion. Chiefs met in a huddle in the evening to discuss how to proceed with the resolution when it is brought back for a vote Wednesday.
