Missing arrival stamp from Niagara Falls

[greenlicious]

Hello all,
I have just received my ITA and I realized that my passport is missing a stamp of arrival in Niagara Falls, ON port when I came back from Buffalo. I did have the stamp of departure, though. I was wondering if this would not be a problem in the future? Any thoughts? Should I drive back to Niagara and ask them to stamp it for me?

Instead you should request entry exit report from cbsa. I think it cost $5.
