Canada drive holiday and finish at New York

[BillyWhizz888]

Hi
I'm starting to look at planning a 3 week trip from the uk

I'm looking to hopefully hire a Dodge Charger to visit
Some family in Canada and then would like to fly over to New York
To spend last few days there before flying home.

I'm unsure about the rules but am I able to fly to Toronto and then fly back
Home from New York.

Also looking for hire car company's that rent dodge chargers.

Thank you
