Thorold and the Welland Canal's Flight Locks
Three of the Welland Canal's eight locks, including the twin "Flight Locks," sit in Thorold, where ships climb the Niagara Escarpment in a continuous staircase, the most dramatic elevation change on the entire canal system. That canal-side position has shaped Thorold's industrial base: aggregate, construction materials, and environmental services companies, including Walker Industries, one of the city's largest employers, operate alongside metal fabricators and manufacturers drawn to the canal corridor. For export shipments crossing into the United States, ISPM-15 certified wood packaging is required at every land border crossing, including Queenston-Lewiston, Peace Bridge, and Niagara Falls. Argos Crating provides the certified crate build and all required documentation in a single engagement.
