Aldi/Lidl occasionally do them for less than GBP5. I did have a couple but they got pretty trashed one night on Loch Chon, eyelets away, edges ripped but they were pretty good if a little noisy. Screwfix have them for a tenner.

Andywinkk makes a 3m x 4m camping tarp. Well made and robust...might be worth a punt?
Not as cheap as a PVC one, but with the advantage that you could actually use it whilst out as well.

Jut curious why you are looking to cover your canoe with a plastic tarp is to protect it or hide it. Its just that I heard covering your canoe this way can have the opposite effect and can cause damage in the long term. I'll try and dig out where I read it probably over on sotp. anyway it is a boat and should be O.K in the rain Seriously, if its to protect from fading in sunlight others I know of won't use a tarp and swear by spraying a couple of times a year with a can 303 aerospace ( I think this is what its called)

Yeah I caught bits on SOTP Dan, that 303 stuff does look good.
The tarp is just to protect it from the sun really, it would be suspended away from the canoe though. I think I read that if you have it touching the boat it creates a micro climate in hot sun and will actually deform the plastic. If I leave a space round it for airflow I think it's supposed to be okay ??
The wall it going to be mounted on gets the sun most of the day so I thought a bit of shade would be good for it ? I read that the 303 stuff revives the original colour and shine so maybe it's just easier to slap that on.
