Suncor announced in October an agreement to buy Teck's 21.3% stake in the bitumen mine, but in December France's TotalEnergies filed an application in the Alberta Court of King's Bench challenging the deal.

On Friday TotalEnergies announced it will acquire an extra 6.65% stake in Fort Hills, and Suncor told Reuters in an email it will acquire the rest as originally planned.

Teck did not immediately respond to a request for comment.
