iPhone 4 Verizon no contract

Ok so I ordered an iPhone 4 off of eBay, the title of the item is "Apple iPhone 4 8GB Black Verizon / Page Plus Smartphone- Clean ESN" and it comes without a contract and it was not bought from Apple or Verizon it is bought from "grabwirelessusa" on eBay. I'm in Canada and I just ordered the phone so I could use it without a plan or a sim card and just use it for WiFi and apps. The item condition is also "Manufacturer refurbished". Is there a way to use it without a sim card or a plan and just unlock it for using wifi and apps and if not how am I suppose to activate it without a contract.
