Pursuant to Circular 072-26, the Montréal Exchange wishes to inform its participants that it will temporarily suspend order entry and trading on the LGB contracts expiring in December 2026 (Z26), March 2027 (H27) and June 2027 (M27) and related strategies, effective as of July 21, 2026, until the upcoming implementation* of the proposed modifications to the LGB contract specification described in the above-mentioned circular.

There will be no impact on the September 2026 (U26) contract. The Montréal Exchange expects to implement such modifications by early September at the latest, applicable to the December 2026 (Z26) contract and all subsequent contract months.
