I used plastic snap-together tiles from costco on the main part of my floor and they look fine. They've been in about 7 years now. There's a small step up to a landing before the door to the house where I used epoxy from home depot. I think it was Rustoleum. It still looks fine, although it's picked up some stains that haven't come out with some casual mopping. One thing I noticed is the concrete cracked slightly and obviously that shows clearly through the epoxy. If the concrete cracks under the tiles it doesn't show.

we bought a 4 yr old home this past October and had the garage floors painted with epoxy paint--the kit where you can add the reflective particles at the end (which we did not do) our painting contractor did the job--they pressure washed then acid washed the garage floors to rid them of any grease/dirt and to open the pores of the concrete to accept the paint we used a beige color--the other was gray I think--and I think they got the kits at their paint store or Lowes--forget-- the contractor was pretty open about the reliability of the finish--told my husband that doing it in cold weather was a little risky and they did have to wait for the temps to be above certain degree..that a lot of the longevity of the paint depended on the quality of the concrete...if it sweated a lot then the paint would probably come off quicker they also had to paint some parts (including brick step in one garage) more than once because they were more porous and sucked up the paint... the problem with this type of paint--or any type really in this situation I guess--is that steel-belted radial tires coming onto that paint can cause it to blister/melt and split.. contractor recommended not using the clear coat because of the slippery when wet nature and the tires' heat--that having it start to flake off was harder to repair than the paint's surface alone--that does not agree with what the other posted said--so maybe I misremembered--maybe it was just the slippery nature that made my husband not put it on... so far ours looks pretty good--but when we wash it out, the floor is slippery--more than a normal concrete I think we have a split 3-car garage I drive straight in to my bay but my husband in a Tahoe has to make a turn into his -- more torque on his wheels and on the floor I think his side is maybe showing some places where small pieces of paint have come off... he plays golf each week with guy whose wife gave him that treatment for present last Christmas--after we had ours done...it was horrible...the guy she hired from Lowe's or Home Depot did not even read the directions...the finish was totally screwed up--made a horrible mess on his garage floor that he spend an entire weekend cleaning off...could not park his car on the floor because of what it would do to his tires... so if you are doing it just read and understand the directions...

I live in Minnesota, my garage is heated. When it was built in 1997 I put two coats of Rustoleum epoxy cement paint, mixed with pumice - to make it slip resistant. I don't know how you have to prep your garage slab - but I can tell you it needs to be dry - paint won't stick to water. I'd wait until the summer - then tape a 2'-3' square poly to the floor. After several days remove it. If it's dark in color, then you have too much moisture in the slab.

That looks to be an excellent no-slip surface that would be PERFECT for winters in Canada! A high-grit surface is excellent for cars, tires, wet slippery things, etc. Did you want to use the garage for cars? Or "living" on? The comment about area rugs has me confused. Rarely would I see a car garage filled with area rugs. As above, the more coats of clear epoxy they put down, the smoother this thing will get. And no, the "leveling" of the wavy concrete is not part of the job - unless specifically requested/paid for. Normally a car garage doesn't have issues with a little dip and wave. A garage conversion into a living space would be make the "leveling" more important - but a real car garage wouldn't be bothered by some wonky concrete...cars don't care.
