None. The speed limit is the limit. If you drive above it you are breaking the law. Simple, really.
If the speed limit is 50, drive 50. If the speed limit is 60, drive 60 and so on.
If it's not the speed limit yes
Depends on where is Ontario your starting point is. Ontario is HUGE. The time to get from Niagara falls Ontario to Pittsburgh is about 8 hours driving the posted speed limit. From Toronto, it takes about 10 hours. KeVin Toronto
You can drive what ever speed you want but if you are over the limit, you may be arrested.
Approximately 700km - 8 hours if you drive 110km/h on the hwy. including 2 washroom breaks - speed limit is 90km/h most of the way. Hope that helps.

No. You are also allowed to drive at speeds below the speed limit. Some highways will post a minimum speed in addition to the speed limit, with the requirement that you use four-way flashers if your speed drops below the posted minimum.
The speed limit is the top speed that is legally allowed. If it is exceeded, you are breaking the law.
Yes it does have one so you couldn't drive the speed you wanna drive.
You can go to traffic school if it is your first offence. After that, you will have to pay a fine.
Always
Whatever the speed limit is.
