Skipping a more general discussion of Alberta versus B.C...

Whether or not it is "gouging", yes, B.C. taxes on gasoline
are higher. Among other differences, there is a "carbon tax"; B.C. prices in general will be about 10 cent/litre higher than otherwise similar locations in B.C., so I plan fuel stops for the Alberta side of the border if reasonable... and the last Alberta community before the border will have higher prices than only a few minutes further into Alberta, based on market pricing forces.
Even within B.C. there are differences in fuel tax rates
. The most noticeable is the roughly 10 cents/litre added to support the transit system in the municipalities served by the SkyTrain; if you drive in to Vancouver from Chilliwack or the Okanagan, I suggest filling up by Aldergrove at the latest, as you'll see prices climb rapidly by Surrey.
Kamloops is a low price island within B.C., but that is unrelated to taxes.
You can see all of this in any map display of gas prices, but knowing these general trends may be helpful.
