$USDCAD - Watching 1.4050 Resistance

It feels like $USDCAD is trying to decide what it wants to be when it grows up. I'm keeping an eye on the 1.4050 level. If we see a clear rejection there, a move back towards 1.4000 seems plausible, but a sustained break above it, especially on a daily close, would obviously invalidate that short-term view and suggest more upside. At 1.40226 right now, it's a bit of a nail-biter, isn't it?
