Is my house around Parliament Hill? Obviously in the interest of protest you can do something annoying, even at 3am, but you can't do something criminal. A train horn goes up to 110dB. If you do something illegal, like blast a train horn enough to potentially cause damage of one kind or another, then you can be arrested. You have to be careful about the actual charge though, because arresting someone vaguely "for public disturbance on Parliament Hill" eventually gets you arresting people for holding up blank pieces of paper while standing in silence too. Freezing the bank account of people who hold signs on parliament hill or people who donate to people who hold signs on parliament hill isn't a part of arresting them for doing something illegal.
