It's budget week.

MPs return to Parliament Monday following a two-week break, and all eyes will be on the federal budget when it's tabled Tuesday.

Here's a breakdown of the week ahead:

Monday

Finance Minister Joe Oliver will hold a pre-budget photo opportunity at a Shoe Company location in Toronto on Monday. Buying new shoes near budget day is a tradition among Canadian finance ministers.

One day before the government presents its fiscal plan for 2015, the parliamentary budget officer will release a new report analyzing the implementation of last year's federal fiscal plan.

The trial of suspended senator Mike Duffy continues Monday. Provocative political commentator and former Sun News personality Ezra Levant is expected to testify. Levant is expected to tell the court about the speeches Duffy allegedly paid him to write five or six years ago. 

Former Tory staffer Bill Rogers is also expected to take the stand. Both men were allegedly paid via contracts handled by Duffy's friend Gerry Donohue. 

The Senate National Security and Defence committee will review the government's anti-terror bill, C-51, on Monday. The committee is scheduled to hear from a number of witnesses including Michel Coulombe, director of the Canadian Security Intelligence Service, and retired Supreme Court Justice John Major. 

And the lawn of Parliament Hill will be busy too, as marijuana proponents gather for 420. The act of civil disobedience is held every year on April 20. This year's event will focus on mobilizing Canadian voters in advance of the fall election. 

Tuesday

The Conservatives will table their budget Tuesday in the House of Commons. What can Canadians expect? 

The government has already revealed many of its election goodies, including the Family Tax Cut – also known as income splitting -- a doubling of the child fitness tax credit to $1,000, and a boosted Universal Child Care benefit. The budget is also expected to feature new money for infrastructure, national security and manufacturing, as well as tax breaks for seniors. 

Thursday

In Vancouver Thursday, the Federal Court will hear from Vancouver lawyer Aniz Alani, who is challenging the constitutionality of Prime Minister Stephen Harper's refusal to appoint senators to fill the 18 vacancies in the Red Chamber. 

Friday

The Supreme Court will hear the case challenging the appointment of former Federal Court of Appeal Justice Robert Mainville to the Quebec's Court of Appeal. The appointment is being challenged as unconstitutional by the Quebec government and Toronto lawyer Rocco Galati. 

The Arctic Council ministerial meeting will be held in Iqaluit, Nunavut on Friday and Saturday. The gathering will mark the end of Canada's chairmanship of the Council. The U.S. takes over the Arctic Council chairmanship for the next two years. While the U.S. is sending its Secretary of State John Kerry to the meeting, Russian will not send its foreign affairs official.
