Our resident chip expert, moose, will probably chime in at some point.

It really depends on how much you are willing to spend. What's your price range? Do you want plastic, Chinese clay (CC), ceramic, clay (that's in order of cheapest to most expensive)?
I'm not sure what you mean by "not stickered, printed if possible". Ceramics are "printed" I guess, but most clay and CC have an inlay which is kind of like a sticker. There are also hot stamp options but those tend to be more expensive.
There are not a lot of options for decent poker chips in Canada to be honest unless you are willing to settle for the cheaper stuff. Some of us (more than others) are kind of chip snobs.
