try Autotrain next time
I know you're leaving today so it's too late, but next time, or on the return trip, you may want to consider Amtrak Autotrain. I've live in Buffalo & I've taken it quite a few times to get to/from Tampa.
It would be cheaper than staying in hotels, paying for gas.
You would drive from Toronto to Lorton, Virginia. The Autotrain departs at 4pm. They put your car on it, and the trip includes dinner, snacks and breakfast and movies. If you get a sleeper car it jacks the price up quite a bit, so just sleep in the seat, which is pretty comfortable. You will then arrive in Sanford, FL (an hour east of Orlando) at about 9am the next day. The price is reasonable, and seems to fluctuate depending on how far in advance you purchase. There is also a 10 percent discount with AAA/CAA card. You pass some pretty/interesting scenery, FBI training grounds, etc.
