Here's my setup when the boy was small.
In Ontario a child's car seat can be mounted anywhere in the vehicle. (I checked with the MTO)
If it's in the front seat the vehicle must NOT have a airbag or it must have the ability to shut the airbag off.
BUT, where ever it's mounted, it HAS to be tethered.
When he's in the backseat, I tethered his car seat to the rear seat belt bolts behind the seat.
