All of WM Canada’s oils used to be made by Safety Kleen; so they were all re-refined, including the synthetics.
Now WM Canada sells the same oil products in Canada and the US made by Warren.
You used to be able to get S-K oils at the chain Princess Auto; but that now seems to be hit and miss. I think Safety Kleen now focuses on bulk sales to fleet organizations - municipal bus services. I know Ottawa’s bud service runs on re-refined oils from them.
