Yeah, to confuse matters, a red spotted eastern can look more like a parietalis than an actual parietalis without the red. Hope that made sense. Even though the "northern" label is erroneous, it probably indicates where they came from, which would make them most likely parietalis'. I think it's common practice to raid the communal dens and ship them overseas in bulk, labeled as "northern" garter snake. More than half probably die during shipping but collecting great numbers at the Canadian dens ensures that at least some will survive the long trip.
