The painted lines on Ottawa's roads are literally disappearing, leading to a surge in complaints from residents and saddling the city with a costly problem to solve.

The rapidly fading road markings have been an issue since 2012, when council voted to save money by repainting them just once a year. A few months later the federal government made it mandatory for municipalities to use paint with low volatile organic compounds (VOC), a more environmentally friendly alternative to the longer-lasting product many cities had been using.

The problem is, low-VOC paint tends to last less than a year on Ottawa's roads, and by spring many markings have disappeared completely.
