If you select multiple provinces in your EE, then they see you as a prostitute and no one wants to marry a prostitute with no loyalty

. Each province have different requirements for selection, some tell you what these are, others don't. You will need to research and see which ones you might qualify for.
Provinces like Saskatchewan does not pick directly from the pool. You will need to fill in their EOI application separately and if you qualify, wait for their ITA.
