• Trudeau formally commits to lifting visa requirement for Mexicans

Parliamentarians will also have to stay in Ottawa longer than previously thought to hear Obama's speech, as the House of Commons wasexpected to rise for summer breakon June 23.The last U.S. president to address a joint session of Parliament was Bill Clinton in 1995.

Former prime minister Stephen Harperpostponed the last North American leaderssummitin January 2015 amid tensions over the Keystone XL pipeline,food labelling and a range of other issues.

PenaNieto'svisit to Ottawa is strictlydependent on Canada lifting its requirement that all Mexican visitors have a visa,a controversial measureput in placein 2009 to curb bogus asylum claims. Thatpolicyhasstrained relations between the two countriesand led theMexican ambassador to Canada to declare that he was"really mad"at the former Harpergovernment for the move.

CBC News has learned that there has been significant progress on this file since the Liberal government's election, something Trudeau promised last summer in the lead-up to the Oct. 19election campaign.

Foreign Affairs Minister Stphane Dionwas tasked by the prime ministerwith finding a solution to this problem in his ministerial mandate letter.
