Most likely color space for scanner?

I have a scanner from 2010 (Canoscan 8800F) which does not include color profiling software. I figure it is using a ‘canned’ profile, as is mentioned here. It scans images to tif files without embedding an ICC color profile. When I read in the RGB values from the tif file, what color space should I assume the RGB values are in? I am thinking sRGB was most common in 2010, but would welcome any thoughts.
