June 6 (Bloomberg ) — The Canadian government’s C$227 billion ($204 billion) budget was passed in the House of Commons after opposition lawmakers accidentally failed to stand up to debate the spending plan. “It passed with unanimous consent,’’ Finance Minister Jim Flaherty told reporters outside the House of Commons in Ottawa today. Legislators were supposed to hold a debate and final vote on the spending plan after Parliament’s finance committee completed its review. By remaining seated in the House of Commons, opposition lawmakers allowed the bill to pass “in a matter of minutes,’’ said Libby Davies, the New Democratic Party member responsible for legislation.
