Principal Architect

It has come to our attention that various international organizations or individuals have been offering false employment opportunities at Aecon Group Inc. Aecon Group Inc. employment policies and processes involve interviews, and candidates who seek employment 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 also do not extend formal offers of employment or execute employment agreements through social media or social chat platforms.
We take this matter extremely seriously and are working with the appropriate authorities to shut down such fraudulent schemes. Please remain vigilant on this matter and report any suspicious outreach to your local authorities and email any concerns View email address on ca.hrm.tc
