Pete,
A true US built SS is in the VIN from '64 - '68 and yes there are measures
even here to make sure things have not been tampered with on any year.
After '68 the SS was on option and can only be proven with an original
build sheet, original invoice or protector plate (exception in '72 the VIN
had engine size and 454 was available only on for an SS). Canada has
documentation for cars built there, but yours was built in Baltimore, MD.
Unfortunately without the documentation, there is no way to prove a true SS
on a '69 as someone could have gone through and installed all the SS
options and features and you could never tell the difference. If you ever
have the interior apart you may find a build sheet tucked into a seat or
else where.

Recently ( two months ago ) I bought a ' 69 Chevelle SS . I'm trying to
determine if the car is a trueSS . The previous owner is 98% sure it is a
true SS . The car has no paper work to prove or dis-prove it is a SS. I
been to web sites that say you can determine it is a SS by the VIN and
other web sites that say starting in'69 you can't use the VIN to determine
if the car is a SS . The VIN for my car is 136379B382206 . Any help or
ideas !
Thanks
