A Question about a Gazebo?

It’s rainy today and I have erected a pop-up gazebo. I am wondering if I could leave it there all night, all week, all month? I have medium size pegs hammered into the four legs and am going to add sand bags.
The reason I ask is, I have a tiny garden. I’d hate for it to take off and cause havoc with the neighbors also tiny gardens. Should I take it down tonight or do you think it is safe to leave it?
It is made from canvas and is a temporary one as opposed to the heavier ones.
