If one of you can claim a job description matching LPN (licensed practical nurse) you can apply under there because their quota isn't full. You can find the description here: http://www5.hrsdc.gc.ca/noc/english/noc/2006/Profile.aspx?val=3&val1=3233
If you can not apply under LPN, then you can start preparing your application but you must wait to apply until July 1st when the caps are set to zero again. If you send it in sooner, they will send it back with a sorry, cap is full.
