In my opinion GBP is building up for a big fall this year, and it has to start with a lower high.
Oil prices are rising, and as much as the FED don't want this, it's happening, and this should be good for CAD.
I can see a rising wedge pattern, we can see spinning tops forming and it looks like we're running out of steam, I believe we'll initially fall back to the 1.7 support / round number.
I'm waiting for my entry, I expected GBP to fall before now, but the BoC unemployment news wasn't supportive last week.
