Eh... I think that passanger seat can go back further. Or you can put down the bucket seat and use one of the back seats. You'd be pulling the kid out from the rear though. Seriously I've done it. I fit three carseats in mine. Took me an hour to get them in right and safely.
Otherwise I think it looks fine but I can only tell so much from the picture.
Dorel technically requires that their seats be a full 45 degrees reclined, but also says they pass testing at 30. Do with that what you will. LOL
The Angle Adjuster is fine for Canada and 5 lbs could be another year of growth if that's a route you want to pursue.
For a two year old as upright as 30 degrees is fine. It's actually safer for older rfing children to be more upright, the 45 degree thing is just so newborns don't have their airways obstructed.
The angle adjuster works really well in the 5 (even lets you put a RFing Radian in the third row!). I'd go that route just because I don't care for the Scenera at all. If you don't mind it, your current set up is fine.
