Patrick Robin of the Prince Albert Police Service was dismissed in 2010 for attempting to prosecute a traffic ticket on his own.
He appealed his firing to the Saskatchewan Police Commission and was reinstated, but the police service appealed and put Robin on leave.
The commission earlier this year upheld the original decision to fire him.
But Robin had continued to receive his regular pay and benefits while he was on leave.
Prince Albert Mayor Greg Dionne says the city is looking at how to get back the money.
"We’re just getting a legal opinion now on who we can collect from,” said Dionne, who is also vice-chair of the Prince Albert Board of Police Commissioners.
He said it's unfair to the city's taxpayers to bear the financial burden of the drawn-out appeal process.
"We believe that the process took too long and we believe it could have been done a lot quicker.”
The numbers released by the police commissioners board show that Robin was paid just over $396,000 in salary from Dec. 17, 2010, to this past April 4. He also received more than $70,000 in benefits.
Police Chief Troy Cooper said in a written statement that Robin’s position has been filled.
Cooper said the last issue remaining is an application by Robin to have Court of Queen’s Bench review the police commission's decision.
That request is expected to be heard in July.
