Light Leakage?

I have been having some light leakage on my film and was wondering what could possibly be causing this. I have a canon rebel EOS GII. Thank you in advance!

I cannot find a picture of your camera model that shows the back. The G and G QD have a film window that allows you to see what film is in the camera. The light seal fails on these windows on all brands of cameras and causes a light leak onto the film. Put some opaque tape over the window and see if the leak goes away.

Place a negative with the light leak over the film gate, emulsion side toward the lens, top of the image to the bottom of the camera and observe where the leak is.

Post a picture of the negative for further help.

Thank you so much!

You might try -- Procure a tiny keychain flashlight that will remain on without the need to hold a button. Place this illuminated flashlight inside the camera and close. Retire to a darkroom. Now begin to examine the camera's exterior. Rotate and look at all the seams. If you see light peaking through, you have discovered the source. You must allow sufficient time for your eyes to dark adapt to be certain that the housing and seams are OK. It takes a good 15 minutes or more for you eyes to adopt. If you are in a hurry, place an opaque eye patch over one eye. This is old trick of sailors, your covered eye will dark adapt. Best of luck!
