We see a few concrete poles but I haven't seen the laminated ones.
Most of the time it is just a PT SYP pole. I guess they grow the pine right up the road so it is easy. I think these are the same 2.5 CCA they use for dock poles. You may not be able to get CCA up there tho.
If you have not seen what they look like here is the site for one of the manufactures.

As for concrete poles I can only think of one section in our city that has them and I think that they were an experiment.
