"Why can't we get that kind of "socialists"?"

We would need an entirely new political party to represent such views, or alternatively to have one of our existing parties change their views dramatically.  Currently none of our parties is all that well aligned with the Scandinavian economic models, and it is tough to even judge who might be closest as, on some matters, the Conservatives are most closely aligned while on other matters the NDP would  be most closely aligned.

In any case, when you look at the big picture Canada's in a comparable position to Norway, we just have more of our wealth held in private funds  (RRSPs, pension plans, etc.) and less in a sovereign wealth fund.  Total net worth per capita of Canadians and Norwegians is comparable.
