I checked out a Radian in Calgary today. I found it very small for my 4.5 year old and am going to wait for a Frontier. The lady at the store said the Frontier is supposed to be much better. I found the Radian very very narrow and my daughter is a skinny little thing, it was also very short from the back to front, like her upper legs were too long, and she is only average height. She was also between the last and second to last slots. The slots for the Radian are 17" and the Frontier is 18.25" so a bit more growing room. The great thing about a Frontier is that once they outgrow it (which will be around 7-8 years for an average girl) it can be used as a booster until 100 pounds. The Frontier is a 5 point harness up to 80 pounds in the US. I am assuming that the carseat is made the same as the US one so it would be safe to keep them in the harness a bit longer than 65 pounds as long as they were still below the top harness slots and their head was below the top of the seat. Plus for the Radian is that it is PINK, my DD really wanted a pink seat. Maybe someone will have a pink Frontier in Canada?

Right now the pink frontier won't be available in Canada. The Frontier top harness height is around 18.25", so it should fit a little longer than the Radian, but not by much since the Radian's top slots are 18" as well.
Most kids outgrow seats by height before weight, and it's pretty unlikely that a child would make it past the 65lbs the seat is rated to in the harness anyways, so chances are pretty darn high that the extra 15lbs won't be used by many kids even in the US. That being said, I wouldn't exceed the 65lb limit on CDN seats.
Torso height does slow by your dd's age for a lot of kids, so she probably has lots of growing room in both seats. Not all seats are comfy for all kids, so if the Radian isn't comfy for her, then that's ok. :thumbsup:
What type of seat is she in right now? You'll want to make sure that she still fits the seat she is using since we're still around 2 months away from the arrival of the Frontier. If she's outgrown the seat she has right now, then you'll have to buy something else. If you'd like some help with seat ideas, feel free to start a new thread with your dd's stats and what vehicle she rides in, and we'd be happy to help you.
