At least 10 dead Canada geese have been collected from a marina in Whitby as town officials try to determine their cause of death.

In an email to CTV News Wednesday morning, a spokesperson for the town east of Toronto said it has responded to reports of dead Canada geese near the Port Whitby Marina this week.

So far, 10 geese have been collected and town staff are working with the Canadian Wildlife Health Cooperative to send the specimens for testing.

“Right now, the cause of death is unknown,” Erin Mikaluk said in a statement.

The town said they are monitoring the waterfront for any other birds that appear to be sick or in distress.

Officials are asking anyone who sees a sick or dead bird to report it to local Animal Services by calling 905-655-0283.

“As a safety precaution, residents should not touch or try to help the birds and should keep pets on a leash to avoid contact,” Mikaluk added.
