Canada's federal information watchdog is poised to share her vision of a 21st-century access regime.

In a report to be tabled in the House of Commons this morning, Suzanne Legault will lay out her recommendations on how to "modernize" the existing Access to Information Act to "strike the right balance for transparency."

The commissioner's report comes just hours before Liberal Leader Justin Trudeau will get his second — and likely final — opportunity to convince his Commons colleagues to back his private member's bid to update the Act to require the department to release data in "machine-readable format."

If adopted, Trudeau's proposal would also shift the onus when it comes to the government's compliance with requests: requiring that "access prevails" in cases where there is uncertainty whether an exception applies to a requested record. His proposal would give the commissioner the power to issue compliance orders.

The bill would also change the rules that govern the secretive all-party committee responsible for overseeing MP expenses and House administration costs to require its meetings, which are currently held behind closed doors, to be open to the public, albeit with "certain exceptions."

After the debate wraps up in the Commons this evening, Trudeau will host a "question-and-answer session" for MPs on his bill, which could go to a vote later this week.

During the first round of debate last November, Conservative MP Dan Albas indicated that the government would not support it, which means it will be defeated unless Conservative backbenchers break rank with cabinet to side with the opposition.
