Canada's Environment Commissioner Fired

The Globe and Mail reports that Johanne Gelinas has been fired:

OTTAWA — Environment Commissioner Johanne Gélinas has been replaced over concerns that her calls for urgent action on climate change took her away from her role as auditor into the realm of advocacy.

The commissioner works as part of the Office of the Auditor-General, which reports to Parliament. Auditor-General Sheila Fraser told members of Parliament on the Commons environment committee Tuesday behind closed doors that she will be announcing Ms. Gélinas's departure at 3 p.m. Tuesday.
[...]
Ms. Gélinas's report last September caused a major stir because it not only criticized the record of the previous Liberal government but also outlined measures the new government should take to address climate change.

If this is about her September report, why has this firing occurred only now? I suppose we'll find out more during the press conference. What should the role of an environment commissioner be?

According to the Auditor-General's site:

The Commissioner provides parliamentarians with objective, independent analysis and recommendations on the federal government's efforts to protect the environment and foster sustainable development.

Encouraging the government to be more accountable for greening its policies, operations, and programs is a key to the Commissioner's mandate.

Auditor-General Sheila Fraser has certainly been vocally critical of government practices in the past and has not been accused of stepping over the line. Was there that much of a difference between her reports and Ms Gelinas'? If so, why was her report approved in the first place?

Update: Canada's environment commissioner says firing a 'complete surprise'

Canada's environment commissioner Johanne Gélinas says it came as a "complete surprise" to learn she was fired, but denied that political interference played a part in her dismissal.

In a statement released late Tuesday, Gélinas said she and her boss, Auditor General Sheila Fraser, had a difference of opinion for almost a year on her role.

"I was considering a future departure, but today's announcement from Mrs. Fraser was premature and came as a complete surprise to me," she said.

Her discussions with Fraser, she added, "were in private, with no interference whatsoever" from the government.

In a statement Tuesday, Fraser said Gélinas was "leaving the position to pursue other opportunities." Fraser also announced a review of environmental and sustainable development audit practices.

But in a confidential memorandum obtained by CBC News Tuesday, Fraser said "sustainable development issues do not appear to have the same impact as our other performance audit work," basing that in part to "how many of our recommendations are implemented."

So, Gelinas wasn't fired for speaking out but because what she did speak out about didn't have enough impact? Curiouser and curiouser.
