OTTAWA, Ont. -- Now that they've had the weekend to digest it, members of Parliament may have questions today about the Harper government's massive budget implementation bill.

The 359-page omnibus bill introduced Friday proposes changes to everything from Canada's food and rail safety regimes to the Judges Act and the National Defence Act.

Critics say it contains little to create jobs, as the Conservatives tout, but plenty of other things that they say should not be included in a budget document.

Here are some other happenings in and around Ottawa today:

-- NDP communities and infrastructure critic Marjolaine Boutin-Sweet will announce her party's priorities for spending on infrastructure, and point out some of the challenges facing municipalities;

-- The Carleton University Centre for European Studies will hold a workshop on the Ukraine and whether European Union policies for its neighbours are effective;

-- The NDP's Canada Post critic Alexandre Boulerice and Denis Lemelin, President of the Canadian Union of Postal Workers, will talk about recent cuts to Canada Post services and expected hikes to stamp prices.

-- The Senate national security and defence committee hears witnesses on how the Canada Border Services Agency determines admissibility to Canada and how it removes people deemed to be inadmissible;

-- Fisheries Minister Gail Shea and department officials appear at a Commons committee to discuss her department's spending estimates;

-- Auditor general Michael Ferguson and assistant auditor general Lyn Sachs will also talk about their spending estimates at the Commons public accounts committee;

-- Canadian Federation of Nurses Unions president Linda Silas and CUPE president Paul Moist discuss the expiry of the 2004 Health Accord and the risk to national medicare;

-- And Gov. Gen. David Johnston and his wife Sharon will host an evening in honour of Robert Lepage, the laureate of the Tenth Glenn Gould Prize.
