kicl, those all look like fine choices and it seems you've done your research on what ncix can make available in Canada without too much extra fee.
A few comments:
1.) Please don't spend that much on a P67 motherboard. You buy ASRock for the budget, not for performance. And do you need that many PCIe expansion slots? Save about $80 and go for something like the ASUS P8P67 Pro. It's a great featured board and ASUS has done a top notch job with their custom UEFI.
2.) The Corsair H70 isn't great. And if you're going to spend near $100 on a CPU cooler, you want it to be top notch. You'll have to do some comparisons with your case, but take a look at the Noctua C14. It's low profile and low noise, but other manufacturer's are having a hard time knocking it off the Top 5 List.
3.) I would not use OCZ for your PSU choice. OCZ makes some great memory and they are dominating the Sandforce SSD market right now, but they're not a PSU manufacturer. The Power Supply is the most important part of your build and you want to make sure you aren't skimping just to save some money. Look to Corsair, like the HX750, or Antec, such as the TPN 750W. Ever since Seasonic started selling direct to the consumer, I've been in love: NCIX doesn't have the X750, but my God is it amazing. The X760 is new, but you'll pay a premium for its fanless superiority.
4.) One question you have to ask is: "Will I ever buy a second GPU?" I say no. Unless you're triple-screening, which is mostly a gimmick, or running at some ridiculous resolution, and you aren't doing either if a new monitor has to go in this budget, you don't need more than the GTX 570. You didn't list what games you play, but it will handle them. Adding a second GPU is an expensive hassle that most people don't need when they're building a brand new system.
That being said, if there's something in the back of your head that just has to have two GPU's at some point, the first thing I'd do is buy the 850 version of any of the PSU's mentioned above. With a hearty overclock and two of the previously mentioned GPUs, 750 pushes a threshold that's best to avoid. Also, the only reason I'd consider AMD over NVIDIA in this case is if you are definitely going dual-card, you'd save going with the 6950's and if you ever do triple-monitor, AMD's Eyefinity is loads better than NVIDIA's 3D Surround. (But if you want 3D, another gimmick/headache IMO, then obviously NVIDIA is your choice.)
5.) If you aren't partial to that case, take a look at what Cooler Master and NXZT have to offer. You'd save some going with the CM 922, but some don't like that industrial look. The NZXT Tempest Evo is another budget-friendly favourite of mine. It's all personal preference, and I do like the conservative look to that Corsair, if you end up getting it, please let me know your thoughts. The only thing a case needs to do is: Have decent airflow capabilities, fit your CPU Cooler and GPU, and not be annoying to work with.
FINAL.) I'm not sure where that leaves your budget or what monitors you're looking at. I can help there as well if you toss some ideas out. I would highly recommend an SSD, but only if a reputable brand (Intel, OCZ, Crucial/Micron) fits in your budget at a capacity that makes sense. NCIX puts a premium on that WD HDD and they don't have a great selection, you might try saving some by looking elsewhere. My personal favourites are the Samsung Spinpoint F4's.
Building a new machine is an exhilerating experience, but take your time! Patience allows you to find the best deals and save quite a bit. Watch BensBargains.net, you may find a better deal even after shipping it from the states. Good luck and keep us updated.
EDIT: The post above me screams cookie-cutter copy/paste, but maybe not. Why_Me's recommendations on the case and motherboard are along the same lines of what I mentioned, but I would not go dual-560's over a 570. It's just not worth it. That CPU cooler is THE budget cooler to get, but it won't let you sit comfortably at 4.8+. Also, Why_Me brings up a good point, don't forget to add ~$20 for a DVD/RW drive if you don't have one to cannibalize, that ASUS one is solid.
