Water Damaged Passport

So I was in Edinburgh back in October and my passport got some water damage. It's still legible and the front was roughed up before it even got wet. The only real damage is with the wavy pages. I had no issue leaving the UK, entering France, or reentering Canada. I was planning on replacing it eventually but a surprise trip came up and now I'm wondering if I need to replace it in a hurry. My family thinks it will be fine but I'm starting to get anxious. My trip is on the 29th of January. Does anyone think that will be the case or am I fine?
