What we know about the proposed free trade deal with Europe announced "in-principle" just over a week ago comes to us through leaks and press releases from those generally in favour of the deal.
And, already there's reason for concern.
The Comprehensive Economic and Trade Agreement (CETA) will no doubt contain some good and bad things for Canadians worried about the security of their jobs or the opportunities for them or their children to find meaningful employment. Any trade deal would.
What we don't know, and can't know until we see the entire text of the deal, is how the two balance.
Hopefully, that will come Tuesday, when Prime Minister Stephen Harper tables the tentative agreement in the House of Commons.
