I doubt that you will notice much difference in the usual expat hangouts. There are fireworks on Sunday at 8pm (

There may be a protest march on Sunday (probably going from Victoria Park to Central), but I doubt it will be the same order of magnitude as a couple of years ago.
The thing that's likely to be most visible, in LKF at least, will be the Canadians celebrating national day on Saturday - that's normally quite a major turnout.
