The Prime Minister's Office says Justin Trudeau and his wife, Sophie Grégoire Trudeau, stayed in a $6,000 per night hotel suite while attending the funeral for Queen Elizabeth II.
The stay at the Corinthia London hotel became the subject of public debate last fall when media honed in on the details of the $400,000 trip, after obtaining documents through access-to-information requests.
But Trudeau's office and Global Affairs Canada did not respond to questions last month about who stayed in the expensive river suite, which features a butler service.
Opposition MPs on the government operations committee asked for a copy of all receipts and invoices associated with the trip last month.
In a statement, the Prime Minister's Office says hotel prices surged significantly ahead of the funeral, and many London hotels were sold out as 500 heads of state and their delegations descended on the city.
The room was booked on Sept. 9, one day after the Queen's death.
In November, Conservative Leader Pierre Poilievre peppered Trudeau with questions in the House of Commons about who stayed in the suite, but he didn't answer.
A press secretary for Trudeau said Thursday that the Queen's death was "a significant event for Canadians."
