Fraud Warning: It has come to our attention that various international organizations or individuals have been offering false employment opportunities at Aecon Group Inc. These individuals will offer to fast track Canadian working visa applications in exchange for a payment. Such offers are fraudulent and intended to steal from the victims.

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
