For over a century, Aecon and our predecessor companies have helped build many of Canada's most famous infrastructure landmarks – from the CN Tower and the St. Lawrence Seaway, to the Calgary Olympic Oval and the Halifax Shipyards. But, perhaps more importantly, we've helped build hundreds of factories, roads, sewers, theatres, book stores, power plants, paint shops, arts centres, offices, hotels and gas distribution networks (to name a few) that aren't so famous.
