No they do not care where you did your hours.
As has been said though, use the hours to your advantage, do some in flight diversions, maintain discipline in terms of speed, heading and altitude and remember to enjoy it!! This is your opportunity to make your CPL training a bit easier by preparing yourself and upping your game.
If you make any mistakes, be honest with yourself, look at the error chain and learn from it. A popular interview question is "have you ever made a mistake while flying, and what did you do to recover from it?"
I would also urge you to consider spreading any hour building over a few locations, it's all too easy to go to one school in the US or Canada for 6 weeks and fly the same routes etc. The first week is always the hardest and being out of your comfort zone is when you will learn a lot. So if you find yourself becoming a bit lazy and flying the route you did yesterday it might be time to be honest with yourself and mix things up a bit.
