CNRLcontinues operations

The CNRL Horizon site has told staff to continue to work. CNRL saidit is monitoring air quality and has been told by Alberta Health Services there is currently no need for a mandatory evacuation.

But contract workers at the site have told CBC News they are concerned for their safety and some are refusing to go back to work.

One worker said the smoke was so heavy his eyes would begin to tear up within minutes of stepping outside.

But CNRL in a statement said the smoke poses no safety risk to workers. Conditions improved this morning and are returning to "sunny and dry conditions" the company said.

On Saturday afternoon, CNRL sent CBC a statement adding, "We are working hard to make travel arrangements for anyone who would like to leave our site with no repercussions from Canadian Natural for requesting to do so".
