If you are still interested, I second the XSPC starter kit. Good bang for buck as for as custom water cooling goes.
BTW, as Prestige suggests, the only decent place to buy custom water cooling stuff in Canada, as far as I know, is Dazmode
. Located in Toronto. I bought my XSPC kit from there, plus a few other things, and service was pretty good. Prices are hit/miss, but it may be cheaper overall than having to pay for shipping from the US. See here
for their custom XSPC starter kits. Start by deciding whether you want a dual 5.25 bay mounted reservoir/pump combo or not.
Seems like now they only offer the Laing D5 pump with the kit. I got mine with a Laing DDC pump. Both get pretty good reviews. The D5 is probably a bit quieter on average, though it is larger. The D5 also has a bit higher max flow rate, but the DDC purportedly has a bit more max head pressure - good if you are doing more components in your loop. Extra flow much above 1 gallon/minute apparently doesn't get you much.
I also recommend you get some Dazmode protector
. This is used in place of biocide and kill coils, etc. Its the only additive you need, and is a great price. Made for Dazmode by Feser. I've been using it for a year and it's been great. No algea, no corrosion. Just mix with distilled water as directed. One bottle, for $7, should be good for 2 fills.
