I stumbled across a Christmas film on television while I was at my grandparents' house in the early 2000s, although I don't know if that's when it was released. It involved a guy who was Santa Claus's son helping him evade some bad guys so he could deliver presents in time for Christmas. The son was a regular 30-something guy who had a son of his own (Santa's grandson) who was about seven years old. There was a chase scene in a factory/mail distribution centre, but the only scene I clearly remember was at the end when Santa takes his grandson off in his sleigh with him as his son watches them fly away.

To eliminate some obvious guesses, it wasn't The Santa Clause with Tim Allen, nor was it Ernest Saves Christmas or either version of Miracle on 34th Street.
