There is one really great company that buys up large tracts of land -- many have been timbered or are in remote areas -- then resells them at incredible prices to anyone who wants to buy them (no credit checks, etc. -- you just don't get the title until its paid for). They will let you pay cash (for a percentage off the total price) or make a down payment and monthly payments -- your choice. Some of the parcels are small (and more expensive because they're in what most people consider more desirable locations) but a lot of them are as large as a few hundred acres.
They will send you a monthly catalog with all their current listings for a low yearly subscription price, but you can find some of their offerings
online (Unfortunately, those are usually the higher priced, smaller parcels. If you look online, you probably won't see the more affordable tracts.) The thing is, there is one drawback on a lot of these. They offer them cheap because many of them do not have timber and or mineral rights (usually "reserved for the crown") OR sometimes access is from a forest right of way in the middle of nowhere. You need to read carefully -- though they are quite honest about all that, and in no way try to cheat anyone. Anyway, the company is
Dignam Land http://www.dignam.com/category/western-provinces/. The catalog is fun to dream over -- we got one for years when we were thinking of moving up there. You can search by region of interest too. Have fun!
