The sturdiness of canopy depends on your choice. You need to keep in mind how it will respond to the breeze or wind. There may be a problem that it will blow away even in normally windy areas. To deal with it, canopies are provided with sandbags to stay up to that wind pressure. It adds more to stability. Ropes and stakes are also additions to the stability of canopy against windy conditions. It is all about adding more weight on your own to add stability to the canopy which depends on the positioning too.
