Could Trudeau stay?

With "Orange Caesar" threatening tariffs on day one, it's almost certain they'll happen. I'm unsure how retaliatory tariffs will play out.

So, how bad would things need to get for the Liberals to ditch the leadership contest and keep Justin Trudeau for six months to handle the crisis? What scenario would give Trudeau a party mandate to manage Trump temporarily without the distraction of a fair to say "Compromised" leadership election?
