Your photos aren't bad, but you can make them a lot better without having to spend a lot of money or know a lot about photography.
The first and easiest thing to fix, is to either shoot (or crop) your photos so that they are a square. eBay's search listing uses a square aspect ratio, your photos will look better against similar items.
Second, if you're mostly selling smaller items, get a white poster board from Dollarama and a roll of painter's tape. Tape it up in a curve, instant cheap back drop. It may not look as great as seamless photography paper, but at 1 dollar this is a huge way to upgrade your photos by eliminating a cluttered background.
Lastly, lighting is one of the easiest ways to improve photos, even if you have a basic camera. Try to have an external source of light beyond just your room light. As you get more into selling, and do higher volumes, you could consider looking into getting stand alone photography lights (about 100-150 for a set), or a light box (about 200). For now, you might be able just to use a lamp with the appropriate temperature bulb, or you might be able to find some external LED lights at Dollarama.
Here is a tutorial that is similar to what I am suggesting:

As far as shipping goes, I would advise with the amount of listings and the variety of items you have, always offer free shipping. The only reason not to offer free shipping, is if you have a significant amount of similar products, and think you can market people to purchase more items in order to lower their overall shipping cost.
You can sign up on Canada Post's website for a "small business" account. You will get slightly discounted rates. You don't have to be a registered business, while I am unsure what their terms of service dictate, practically speaking anybody can sign up.
Buy a scale so that you can weigh your items and have an idea of what they will cost to ship, that way you can put the shipping in the actual price without worrying about under or over charging. You can buy a package scale for under $50. I find it is pretty easy to budget for USA/Canada shipping, because the prices are usually similar so long as the item can go tracked packet to the USA.
Canada Post also sells flat rate boxes that can be used for items under 5 KG within Canada. They are almost never cheaper to use than printing a label. They are a useful fall back because you know if an item fits into a flat rate box, that you have a price ceiling where you can ship it for the price of the flat rate box.
Shipping lettermail is the way to go within Canada for smaller items. The benefit of shipping lettermail is that you can lower your margins by about 13 dollars an order, which either allows you to make a greater profit, or offer a more competitive price and sell more items faster. The downside is that you are not protected if a buyer claims they did not receive the item. Depending on what category you sell in, the amount of lost items will vary. Eating those losses are the cost of doing business. So you have to determine whether you have enough incentive to operate this way. For most people, it makes sense because the additional sales/profit they make exceeds the added expenses of having to refund lost packages.

Your actual listings are fine, the only constructive criticism I can provide, which would be a huge reach - would be to use 'You' centered writing instead of 'We'.
