Here's a timeline of how the SNC-Lavalin affair unfolded.

The process to bring in a third shipyard to the National Shipbuilding Strategy is expected to start next month.

The environmental activist and former head of the World Wildlife Fund has been reinstalled to help Trudeau get re-elected, Scott Thompson says.

Butts, a close long-time friend of Trudeau, resigned in February amid the SNC-Lavalin controversy, citing that anonymous sources alleged he pressured former Justice Minister Jody Wilson-Raybould to assist the Quebec engineering giant to be considered for an agreement akin to a plea bargain.

Specifically, she was right in not awarding SNC-Lavalin a special deal in the first place.

The Vancouver-Granville MP hasn't decided whether to run again after getting kicked out of the Liberal caucus, but some say she has what it takes to win.

In an interview with the West Block's Mercedes Stephenson, the former attorney general also said young Indigenous women are feeling 'empowered' amid the SNC-Lavalin scandal.

In a letter shared with the Liberal caucus on Tuesday, Wilson-Raybould defended her commitment to the party's pledge to do politics differently.

Former attorney general Jody Wilson-Raybould warned in a series of text messages with Gerald Butts that there would be Indigenous anger if she was removed from the post.

Wilson-Raybould has testified that the prime minister and his advisors tried to pressure her into approving a remediation agreement for SNC-Lavalin, the against the Montreal-based engineering firm facing fraud and corruption charges.
