When I looked up other posts that referred to Accountemps, I found that they also had done another survey of 277 workers in Canada that was reported on October 25th.
The bar chart shown above compares results from this survey (in red) with those for the United States (in blue). Click on it to see a larger, clearer version. For Canadians, 29% feared making errors on the job (versus 28% in the US). Dealing with difficult customers or clients was feared by 17% (versus 18% in the US). Speaking in front of a group of people came third at 16% (versus a tie for fourth at 13% in the US). Conflicts with coworkers was feared by 14% and ranked fourth (versus 13% in the US). Conflicts with your manager was feared by 12% and ranked fifth (versus 15% and third in the US).
A post by Jenna Charlton at Workopolis.com titled What scares us the most at work? confused things by first linking to the US survey but then quoting three percentages from the Canadian survey.
