CADUSD - Watching the 0.7165 area again

Been keeping an eye on $CADUSD and it seems intent on retesting the 0.7165 support. We've bounced off it a couple of times recently, so it's clearly got some significance. If it holds, we might see a gentle grind back towards 0.7180 or even 0.7200, nothing spectacular but a nice relief bounce. The risk, naturally, is a clean break below 0.7160. If that happens on any decent volume, then all bets are off and we'd likely be looking at a move towards 0.7140 or lower pretty quickly. It's one of those setups where if you're wrong, you'll know it almost immediately.
