Poly-B in Vaughan homes
Polybutylene plumbing was commonly installed in Vaughan homes built between 1978 and 1998. If your home was constructed during this period, there's a possibility it contains poly-B pipes. Many insurance companies in Ontario now have specific policies regarding polybutylene plumbing, including potential surcharges or requirements for replacement. Learn more about poly-B →
Vaughan has the highest poly-B-era share of any city in this directory: 43,780 of its 103,915 occupied dwellings, or 42.1%, were built between 1981 and 2000 according to the 2021 Census. Before that it was barely built up, with only 7.6% of today’s dwellings predating 1981, and the boom carried on after 2000.
That makes the useful question in Vaughan less “is my house old enough?” than “was it finished before or after the late 1990s?”. Vaughan belongs to York Region, part of whose water comes from the City of Toronto’s treatment system (Toronto drinking water report). Plumbing is a compulsory trade in Ontario, and certified plumbers and apprentices can be looked up on the public register (Skilled Trades Ontario). The Toronto & GTA guide compares Vaughan with the other 905 cities and lists published Ontario prices.

City-wide
The census groups construction years into periods, so 1981–2000 is the closest match to the 1978–1998 poly-B window.
