For which courts? Canadian rulings would not be considered precedent-setting in a Saudi court.

Its precedent settings i.e. if google follows it, then china and saudi court can ask them to do the same since these kind of rulings become fair game.

Chinese and Saudi courts can do that to the extent the local law allows them to independent of whether Canadian courts do; Chinese and Saudi courts are neither bound nor empowered by Canadian precedent (I doubt either would even treat it as persuasive precedent, much less binding.)
