SteelCity44:I have the Graco My Size70, and I'm happy with it. We had a Chicco infant seat. The Graco was just as easy to install. Yes, the one clip takes a little extra effort to get it to snap in, but it does go in without too much of a struggle. Tightening the straps isn't fun, but I just always keep them tightened. With him in random bundling clothes, I like it to be set to the right thickness anyway so that I know he's not over-bundled.
My Size and Size4Me are not available in Canada. OP, the Radian and the Clek Foonf are pretty much it for rf to a decent age here, followed by the MyRide. Britax isn't great, it's outgrown rf quickly, and not great unless you have a shorty (like >50%) The rest all have fairly strict and short standing limits. Snugglebugz has one model/pattern of Radian on sale right now.
