I wish we could downvote replies like in Reddit; I'd be doing a lot of downvoting on some of the replies you've received already, particularly from those who are ASSUMING that you are trying to get pay TV for free. But that said, you mentioned the satellite dish you have, but gave no details so we don't know what you have now. It may be that all you will have to do is upgrade the LNB on the dish (but not the dish itself) and the receiver. Depending on what you get it may only cost between $100-$200 (not sure if prices are higher in Canada or if you get hit with duty if buying a receiver from the US). People are correct in saying you won't get pay cable channels but you probably knew that already. But there are still lots of channels on true FTA.
My one piece of advice would be to find a receiver that can record channels (PVR capability) because some of the channels that you may want to watch can't be viewed in real time on the receiver, but if you record them and then take the file to a computer and play it in VLC or Kodi then they may play just fine. Or you may need to run the recording through ffmpeg to make it playable (either to reduce the required CPU usage or to fix the audio). Alternately you could use a computer with a satellite tuner card as a receiver but that gets a lot more expensive and it's not really for those who don't know much about computers and don't want to learn. You don't have to be a major computer geek but if all you ever do on a computer is read email and visit web sites (and you had no idea what I was talking about when I mentioned ffmpeg) then you'll probably want to stick with a receiver.
As for a dish, they don't always have to be expensive. Take a ride in the country and if you see one in someone's yard ask if they are still using it. Particularly in the case of large C-band dishes (which are the best kind to have), some people would be happy if you would just haul them away and others will sell theirs for the scrap metal value, only problem there is that some people seem think their dishes must be made of gold. Also some people will try to sell you their old receivers, and you have to gently remind them that TV converted to digital about a decade ago so if the receiver is older than that it not really useful anymore, anymore than an old analog TV is. If they don't want to let their dish go write your name and number on a card and ask them to call you if they change their minds. I have gotten a couple of dishes where I left my number and out of the blue I got a call weeks or months later because something happened, in one case I think the guy got married and his wife could not stand looking at that "big ugly dish" out of her kitchen window. You may get turned down a few times but you only need someone to say yes once to get your feet wet. Just one pro tip, if the dish isn't reasonably close to the ground don't even ask unless you can rent a crane, and if it's a big fiberglass dish don't ask unless you have at least three strong people to help lift it off the pole (you MIGHT be able to work it off the pole with two strong people but you will probably drop it and damage it or even injure yourselves, and you'll probably have a backache for a week!). The easiest kind to remove are the metal mesh dishes, particularly if they are made of aluminum (also aluminum doesn't rust).
Of course all that assumes that you are not in a municipality or a HOA (do they have those in Canada?) that will not let you have a big dish. I remember at one time reading that they were trying to make it illegal for homeowners to have big dishes throughout Canada because the CRTC had a bug up their butts about people being able to watch American programming without restriction (probably forgetting that most Canadians live within about 100 miles of the border and many can receive American channels with a TV antenna) but I don't THINK that ever went anywhere, but I can't be sure.
