Trump has endorsed it already.

For the Canada-US portion there are relatively few changes from NAFTA.

The main talking points would be a slight opening of Canada's dairy market, in exchange for which the US will crack open its sugar market.

There's some new language on genetically modified foods and the like and a few other 'modernizations'.

The bigger changes are on the Mexico side, and include a variety of changes to empower Unions [[make sure they aren't just corporate puppets) and specific provisions raising the minimum of wage of Mexican auto workers.

The rest I will leave for you all to peruse at the above link, happy reading.
