What drives custom drain covers in Thornhill (York Region (Markham / Vaughan)) is Commercial office and retail, healthcare, tech and professional services, light industrial and condo/mixed-use development. The work concentrates around Yonge Street corridor, Centre Street, Doncaster and Steeles employment lands, Allen Road/Highway 7 commercial strips.
