This is the best summary I could come up with:

Parliamentary Budget Officer Yves Giroux disclosed to a House of Commons committee on Monday that the government has internal analysis of the economic impacts of its consumer and industrial carbon pricing programs that it is keeping under wraps.

The Official Opposition seized on the issue Tuesday during Question Period, where Conservative Leader Pierre Poilievre and four of his MPs repeatedly accused the government of a cover-up and muzzling the budget watchdog and demanded the minority Liberals release their internal findings.

However, rather than addressing those questions, Prime Minister Justin Trudeau and his colleagues responded by pointing out that Mr. Giroux has belatedly acknowledged an error in his own report and deflected by accusing the Conservatives of gagging their MPs on the abortion issue.

Mr. Trudeau maintained his government’s position that eight out of 10 Canadian households are better off with the carbon price system because the rebate they receive is greater than what they pay for the fuel charge.

In an interview Tuesday on CTV’s Power Play with Vassy Kapelos, NDP House Leader Peter Julian said the government should release the internal report.

The Parliamentary Budget Officer has faced immense criticism from the Liberals since the Canadian Press reported last week that he quietly notified Parliament about an error in his impact analysis of the consumer carbon price.
