It can be difficult to find a one way truck rental to rent a 16 feet cube truck from Canada to the United States.

Because rates can change so quickly, based on availibility, it's almost impossible for me to give you specific pricing information that would be accurate. I checked for truck rental and moving van rental companies in the Ottawa area; this is what I found: (keep in mind that availability can vary depending on the dates and times that you're looking for)

Budget Truck Rental -- no drop off in Orlando available

Discount Car and Truck rental - no option for a one way truck rental to Orlando

National Car and Truck Rental - no option for a one way moving van or truck to Orlando

U Haul - They had no 16 foot trucks for rent, but I did find a 17 foot truck (holds up to 5780 pounds)

The pricing includes up to 6 days of use and 2674 kilometers.(any additional km are $0.40 each)

You can check pricing for specific dates, times and vehicles right on their website - www.uhaul.com (make sure to put in your postal code for the location search).

There was no mention on the UHaul website reservation system about whether or not their prices includes taxes. They did list a $5 environmental fee (details stated "The Customer money collected as an environmental fee is expended to reduce the negative impact of our business on future generations. Aerodynamic fuel saving truck skirts, the fuel economy gauge, storage re-use centers, environmentally friendly truck wash soap, are examples of where these funds go.

Hope this helps!
