Well that's one sure way to fuck the highway, give access to more speed to people who have zero clue how to drive. So we'll have more accidents, slower highways at times (ironically enough).
In a few years they'll say "oops, we made a mistake" and try to pretend that they're going to do something about it.
They already slowed things down on the QEW near the CNE at Dufferin Gates. I think the DVP has some repairs this week, not sure how long that is going to go on for.

Dude, you need to take a chill pill. A 110 km/h speed limit on some sections of 400 series highways is not the end of the world. For starters, highway (or roads in general) have their own "natural" speed limit, regardless of the posted limit. It's referred to as the 85th Percentile Speed. The 85th percentile speed is the speed at or below which 85% of the free-flowing vehicles travel.
Not sure how old you are, but here's a little history of speed limits in Ontario. Note the part I've highlighted.
Ontario's first province-wide speed limit on rural highways was introduced in 1903 at 15 mph (24 km/h). The speed limit was increased to 25 mph (40 km/h) by the early 1920s and increased further to 35 mph (56 km/h) by the late 1920s. In 1937, the opening of the new Middle Road superhighway between Toronto and Hamilton prompted another review of the speed limits on Ontario highways. The speed limit on most rural highways was increased to 50 mph (80 km/h) in May 1937. During World War II, the speed limits were temporarily lowered to 40 mph (65 km/h) to conserve Canada's fuel supplies. The next speed limit increase took place in 1959, when the speed limit for passenger cars using the new superhighways such as Highway 400 and Highway 401 was changed to 60 mph (100 km/h). The speed limit for trucks and heavy vehicles on the superhighways was increased to 55 mph (90 km/h) in 1959. On some high standard two-lane highways, the speed limit for passenger cars was increased as high as 60 mph (100 km/h) in 1959.
In the late 1960s, the speed limit on the 400-Series Highways was increased again to 70 mph (115 km/h) for passenger cars and 60 mph (100 km/h) for trucks and heavy vehicles. During the energy crisis of the mid-1970s, the speed limit for passenger vehicles was changed back to 60 mph (100 km/h). The energy crisis also brought about the reduction of speed limits on most conventional highways back to a maximum of 55 mph (90 km/h). During the conversion to Metric measurements in 1977, the speed limit on most conventional highways was reduced even further to 80 km/h. Since the 1970s, the speed limit on Ontario freeways has generally remained at 100 km/h (60 mph), while conventional highways have generally remained at 80 km/h (50 mph).
Rest assured, chaos will not ensue with a 10 km/h (6.21 mph) increase in the speed limit.
