Hello,

We'll be driving from US to Toronto, and next day we are going to drive to Ottawa for few days.
When I'm using google maps it tells me that the road between Toronto and Ottawa is partially toll road, and when doing more research it says that it has automated license plate reader. I'll be driving in a rental car. How will that work? Am I going to be hit with the 'penalty' from my rental car place for having unpaid tolls?
There are no booths to pay the tolls in Canada?

Thank you
