Is there any way I can get Wi-Fi during my two month trip?

I'm going away over the summer for two months in Ottawa, since my parents bought a summer home there. They do not want to buy another Wi-Fi package there if we're only gonna be there for 2 months out of twelve. They think it's a waste of money and tbh I don't have the money right now either. But I don't think I'll be able to live without Wi-Fi. So many friends I have to stay in touch with. Please help! I'm going bring my iPhone 4S with me (8 GB) and I was wondering if there's anything that would get me Wi-Fi that I could buy (nothing to expensive!) and not data either… I can't afford that big of a phone plan. I heard Wi-Fi usb's work? Would that work for my phone or just the computer? Please Help ME! Anything portable Wi-Fi that will work for my phone and where I can buy it.

If you have 8GB of data with your phone then use the phones modem connected to your laptop that is if you are taking a laptop. You do not say.
You could try by giving a few more details.

Usually starbucks, mcdonalds, etc, all have Wi-Fi you can use. Get a cup of coffee and a seat.

Pocket Wi-Fi or OM4G if you want. As stated before you can also use your phone as a modem.
