The trial into the deaths of two temporary foreign workers at an Alberta oilsands project has been delayed for a year because a Chinese company is arguing it shouldn't be included in the case. Sinopec Shanghai Engineering...SSEC Canada and Canadian Natural Resources...face 53 charges under the province's Occupational Health and Safety Act. The companies involved in the project were to go to trial Oct. 3, but the case has been put over until Oct. 1, 2012 — more than five years after the workers died on the job. Alberta Justice says Sinopec has been arguing it has no legal presence in Canada and is taking its fight to the Court of Appeal. Canadian Natural Resources asked for the trial to be delayed because it wants Sinopec to be included in the case. The Crown objected to the delay, but the judge granted it.
