In Ontario, I believe our highway speed limits are low simply to increase ticket fees. The police got photo radar vans a couple of years back, instantly the average speed of the highways dropped from 120km/h to the posted 100km/h limit. The public didn't like this, there was talk of raising the speed limit to 120 (apparantly the highways were designed to safely handle this), but in the end, the government simply got rid of the photo radar vans. The limit remains 100km/h, everyone returned to driving at 120+.
On average, I'd say I see one cop car with someone pulled over in 10 hours of driving. Actually, I probably don't even see that many. In the same amount of time, I see 4-5 drivers doing 150+. It's extremely rare to see someone doing less than 120 unless there's heavy traffic.
