Market Document Changes Available for Review in Baseline
January 16, 2026
The Market Manuals and supporting documents that are available for review in this Baseline are posted on the Pending Changes Documents webpage.
The IESO runs the baseline process four times per year to revise market manuals and related documents that change because of recently approved Market Rule amendments or technical system changes.
Details of the document changes can be viewed in the Baseline Plan. Comments for Baseline 55.0 can be sent to pending.changes@ieso.ca by January 30.
