Probably yes. We have some familiarity with some of the universities in Canada.
For schools near Oregon, but in a slightly foreign country a bit to your north, you might want to look at UBC, U.Victoria, and Simon Fraser U. U.Victoria is quite good and has the mildest winters in Canada (UBC and SFU are similar in temperature, but get more rain in the winter than U.Vic). The University of Calgary and the University of Alberta are also quite good (but with colder winters).
Otherwise you are probably looking at schools quite a bit further east, and therefore quite a bit further away. Toronto, Waterloo, and McGill are excellent. All have real winters. If you want to go all the way to the east coast (quite a distance if you want the east coast of Canada) then Dalhousie is another possibility.
The cost of these may vary, with the most famous being somewhat likely to cost more. Also, different provinces may have different degrees to which they will subsidize prices for international students versus wanting to make money from international students. Remember that prices are listed in Canadian dollars, and keep the exchange rate in mind.
Admissions in Canada is largely based on stats. With a 4.0 unweighted GPA and 1500 SAT your chances would be quite good for most of these schools. At this point I am not sure how competitive admissions is for international students majoring in CS at the highest ranked schools, which for CS would be UBC, Toronto, Waterloo, and McGill.
