This follows a messy day of weather in the region, with freezing rain responsible for dozens of crashes yesterday.

On Sunday morning, freezing rain conditions also disrupted LRT service between Conestoga Station and Waterloo Public Station.

In a statement, Keolis Grand River says ice accumulated on the overhead wires on an isolated area of the alignment.

Full ION service resumed by Sunday afternoon and is running normally this morning.
