Aecon Group Inc. employment policies and processes in Canada involve personal interviews, and candidates who seek employment with us are never required to pay us any sum of money. To do so would be contrary to our business conduct guidelines and ethical practices. We take this matter extremely seriously and are working with the appropriate legal authorities to shut down such fraudulent schemes. Read more here
