Kingston to Montreal takes between 2.5 and 3 hours, depending on traffic and how fast you drive. Getting there is dead easy. Get on the 401 East, and stay on it. Eventually you'll end up in downtown Montreal. (In Quebec the 401 becomes Hwy 20.)
Keep in mind that Montreal has a lot of construction tie-ups, so if you have to be there at a specific time, leave yourself a bit of leeway.
