Of six entries on a document detailing Windsor Mayor Drew Dilkens's travel expenses in the first quarter of 2015, a three-day trip to Frankfurt Germany is the most expensive.
The trip to Germany from March 5 to March 8 cost $5,596.51.
The second biggest line item is a trip to visit officials at bus maker Proterra in South Carolina last January. That cost the city $1,797.42.
The other four line items are a trip to Washington D.C. for the Congressional Gold Medal Ceremony, and three conferences in the Greater Toronto Area for mayors and regional chairs.
The two-day trip to Oakville in February for the Large Urban Mayors Conference is the smallest line item at $614.40.
Dilkens is voluntarily posting his travel expenses online on a quarterly basis. "It's important to be up front with the expenses I incur on behalf of the city."
