Waterloo’s Ezra Avenue was so quiet Wednesday, it was hard to believe what had been going on there just 24 hours earlier.

To see the only remaining sign of the massive St. Patrick’s Day party that brought an estimated 5,000 revelers to the street, you’d have to look down and spot a stray cup or discarded piece of grey clothing.

And you’d have to spot it before the Wilfrid Laurier Eco-Hawks did.

“It’s important for us to make sure that we are cleaning up after ourselves,” said Peters, the co-ordinator of Laurier’s environmental group, which spent some time Wednesday picking up garbage on Ezra.

Waterloo Regional Police did not provide a specific breakdown of their activity on St. Patrick’s Day, but said there were few arrests and no serious incidents during Waterloo’s festivities.

One thing they did notice was a spike in the number of impaired drivers, as five arrests were made for that activity on regional roads.

“There’s some work to be done around people receiving and accepting that message that they need to be finding alternate means home,” said police spokesperson Alana Holtom.

The most common St. Patrick’s Day offence dealt with by police in Waterloo was carrying an open container of alcohol in public.

In Guelph, police reported issuing 37 liquor-related offences across the city on Tuesday.

Four arrests were made for public intoxication, with public urination and impaired driving leading to one arrest each.

Guelph Police also responded to eight noise complaints.
