Resolution Criteria:

1. The trade agreement is with another Canadian province or territory.

2. It's for a new agreement, not a renewal or minor amendment of an existing one.

3. All parties to an agreement will be marked as correct answers. For example, if ON, QC, and NU announce a new trade agreement, all three would be selected as correct answers.

4. The market can resolve with any number of correct answers, from 1 up to all 13.

5. In case of ambiguity (e.g., if it's unclear whether an agreement qualifies as "new"), I will make a final decision based on the spirit of the question and available evidence.
