But his office maintains he's fully engaged in the file — it's just that he's more interested in trying to produce results than photo ops.
The NDP leader had planned to host a private meeting Thursday evening at the official Opposition leader's residence with 20 chiefs, including Assembly of First Nations national chief Shawn Atleo.
However, the meeting was shelved late Thursday as the chiefs continued wrangling among themselves about whether to attend Friday's meeting with Prime Minister Stephen Harper.
Mulcair spoke instead by phone with Atleo.
"Chief Atleo was apologetic. Mr. Mulcair was understanding," said the leader's spokesperson, George Smith.
Reporters and photographers had not been invited to the cancelled Stornoway gathering because Muclair had hoped the meeting would be "productive."
"We don't want this to be a spectacle," Smith said prior to the meeting's cancellation.
Mulcair has been noticeably absent from the parade of politicians, including two former prime ministers, who have visited the island where Attawapiskat Chief Theresa Spence has been on a liquid diet to back up her demand for a meeting with Harper and Gov. Gen. David Johnston.
That has led to some speculation that Mulcair was deliberately keeping a cautious distance from the chief, whose financial administration of Attawapiskat has been called into serious question by a leaked audit, and from the grassroots Idle No More protest movement, whose traffic-blocking tactics have infuriated some Canadians.
However, Smith noted that Mulcair did send a "strongly worded" letter to Harper last month, urging him to act on the message of the Idle No More movement by re-engaging with First Nations and to "act swiftly" to avert a "personal tragedy" for Spence.
Moreover, Smith said numerous New Democrat MPs have visited Spence, including Charlie Angus, whose northern Ontario riding encompasses Attawapiskat, and Paul Dewar, whose Ottawa riding encompasses the island on which Spence is currently encamped.
As well, deputy leader Libby Davies, NDP whip Nycole Turmel and a delegation of 16 other MPs have been sent to confer with Spence during her protest.
Smith said Mulcair has also had a "long telephone conversation" with Atleo, in addition to Thursday evening's call.
