I am preparing to purchase a Canon 10-18 IS lens and my question is: If I put a UV Haze filter on it, will it vignette?

It depends on the filter, there are special filters just made for the use with wide angle lenses!

The "ultra-thin".

Rockwell's EF-S 10-18 review included the following assessment: There's no problem with vignetting, even with thick rotating filters.

I bring this up because I just spent 2 weeks finding the right tool needed to get an ultra thin filter off a lens. I've heard in the past they can get stuck with this being the first time I'd encountered the phenomena myself.

I have the Canon 10 - 22 and keep a UV filter on it at all times (for protection) and there is no vignetting at all. When I first bought the lens I only put a cheap (and thick) UV filter on it but now use a (high quality? hmmm...) thin one and neither of them have caused any problems at all.

Speters has the right answer but, why a UV filter? Lens "protection?" The best lens protection is a lens cap and a lens shade. If the lens falls from your hand God is the only protection you could have. If the filter is dirty your pictures will be a disaster. I have never used a UV filter and in my humble opinion someone came up with this idea to sell more UV filters which photographically speaking are totally useless today.
If you use a polarizer keep in mind that some areas of the sky will be polarized while others will not when using the wide angle lens.

I have no problems with thick filters. They are also much easier to put on and take off.

Don't put a UV Haze filter on it. They don't do anything except cost you $$ and if it's cheap they will just be another piece of cheap glass to distort your image. The only filters I'd use for that lens would be CP (polarizer) or ND (neutral density). If you stack 2 filters on that lens at 10mm focal length, then yes, you are likely to have vignetting. They do make thin ND filters that I would suggest you buy. I made the mistake of buying cheap ND filters that require me to stack 3 filters to get 9 stops and they vignette pretty bad. Next time I'll buy larger (82mm) filters to fit my 77mm lens and put a step down ring on it and I'll buy ND filters that are thin and will take only 2 stacked to get me 10 stops.

Hard to say. Depends upon the filter frame thickness. The EF-S 10-18mm uses a smaller diameter filter than most ultrawides (67mm if memory serves), so might be more susceptible to vignetting.

Seems silly to me to put a "protection" filter on a sub-$300 lens. A quality multi-coated filter is going to cost about 25% the price of the lens. A cheap single or uncoated filter will ruin the image quality of the lens.

Better use of your money would be to buy the matching lens hood and use that. It will do a better job "protecting" the lens, than some thin, fragile piece of glass ever could.

In fact, if you do choose to use a protection filter on it, you probably should make a point of using the hood, too... to protect the filter!

The problem with step rings is that they get in the way of fitting most matched lens hoods, which are often more important to use than the filters, might even be needed to get the best out of and to protect the filter!

Back when I was shooting film and needed dozens of different types of filters, I used step rings so that I only needed a couple sizes. But the step rings were a real pain in the arse and I won't use them with digital, since far fewer types of filters are needed (basically just CPL, ND and "protection"), so it's not a big deal to just buy them in the various sizes needed for my lenses.... no step rings needed.

Actually, I do still use some step-rings.... but only in the "filter stack" that I use to store the various sizes of filters needed for my lenses (55mm, 58mm, 67mm, 72mm and 77mm). That makes for compact and very safe storage of the filters.

BTW, quality 82mm filters tend to be significantly more expensive than 77mm or smaller.

The problem with "thin" filters is that some of them don't have front threads, so can't be stacked or have a standard lens cap installed to protect them.

Also, thin filters are typically more expensive, more prone to getting stuck, and more difficult to get a good grip on to unscrew.

I use mostly B+W filters... and their standard frames are thinner than some other brand's.

The obvious would be to use a filter wrench. Adorama, B&H, etc, very inexpensive. Small and large. Need-to-have item.

To fit an 82 mm filter on a 77 mm lens, you'll need a step-up ring.

Here is some information on filters.

I stand corrected. My apologies.

In general, the answer would be no.
