That's why three bursts that have taken place over the past few days are causing concern and raising questions about the condition of our mains.
The latest mini-flood happened early Thursday morning, when a water main burst at Eastern and Broadview Aves., filling the always busy intersection with a small torrent of H2O.
Water also rushed through a Kingston and Markham Road neighbourhood on Monday, flooding residential streets and damaging at least one home.
And on Wednesday, it happened again, this time during the height of rush-hour traffic at Lakeshore and Spadina.
The subsequent flood left drivers restricted to only one lane.
"We can't get to our meeting on time, so it's not good," remarked one man, late for an appointment.
Despite the inconvenience to motorists, water main breaks happen quite often in Toronto. In fact crews respond to 1,600 to 2,000 every year, partly because the water mains themselves are so old.
"We have over 5,000 kilometres of water main underneath the city, so half of that is more than 50 years old," explained the city's Brad Ross.
"There have been water rate increases across the city that council has approved, and that money is going to replace and repair this aging infrastructure," he adds.
