The ERCB has removed production constraints on Suncor's Firebag project.
The restrictions were lifted after Suncor made improvements at the site, in regards to high hydrogen sulphide emissions.
They've been in place since September of last year, as the ERCB said Firebag didn't comply with board requirements.
Suncor was forced to keep Firebag production at 42-thousand BPD.
