The documents do not include specific details on job losses. DFO, which has sustained repeated deep cuts to its science program over the last two decades, now must prepare for further cuts.

The Fisheries Resource Conservation Council, an advisory body that collects the views of fishermen to help make better science decisions, has been disbanded, according to Newfoundland New Democrat Member of Parliament Ryan Cleary.

"When you axe this, you take away a critical, a crucial voice for fishermen," said Cleary.

It is unclear how DFO will fulfil its many legislative and regulatory obligations.

The leaked memo follows on the heels of other recent announcements that the Canadian Government will not longer fund the Canadian Environmental Network, and will seek to cut more than 700 jobs at Environment Canada.
