Residents are worried about a potential increase of E. coli because the City of Ottawa won't install wires to prevent birds at Britannia and Mooney's Bay beaches this season. The wires were installed three metres above sections of those beaches a number of years ago to help prevent the congregation of gulls, which are linked to driving up E. coli counts in nearby water. The city said the wires will not go up this summer as it searches for other ways to manage seagulls and other birds.
