There should be a number that are happy to take your Loonies. I am guessing about some of these as to Canadian shipping, but doubt seriously that it will be a problem.
Performancebike.com deals in moderate level bikes. Some very decent deals. Coupon codes can be found regularly on the web for 10% off or more.
SierraTradingPost.com. I have purchased a few things, but no bikes. Very happy with each transaction. They often have some very decent closeouts. I've seen Colnago, Kestrel (Evoke) and some others over the last year or so. Check the web for coupon codes as much as 30% off.
For upper end, my favorites include:
Jensonusa.com (I've had a few service glitches with them, but generally good). I believe they have some Look 555s and such on sale, and usually have moderate to upper end bikes available.
Pricepoint.com. Consistently the best service I've had, period. They have some house brand bikes that look pretty decent and may be worth a look.
Excelsports.com and Coloradocyclist.com. Real shops that do an OUTSTANDING job on their builds. A lot of mail order outfits ship them to you dealer ready (factory built) but these dudes build them from scratch and know what they are doing. I have purchased a Lightspeed from each and both were ready to ride (almost perfect) right out of the box. Five stars.
Competitive Cyclist has a good reputation but I've never had the pleasure. They have some closeouts on Colnagos and Cervelos right now, I believe.
Hi-Techbikes.com in San Diego seems to carry Kuota and Litespeed and has a good rep, but again, no background with actual purchases.
In my opinion, the upper end shops have one distinct advantage on non-closeout (package) bikes; you can select your parts picks and upgrade. Saddles, wheels, compact vs. traditional cranks, etc. Can ultimately save you a lot if you like a certain bike but don't care for the parts and will want to trade up. You also don't have hassle with the swaps.
Here's my recommendation:
(1) Absolutely know your measurements. Be 100% positive. If you have a bike you like right now, use a clothier's tape to get your numbers (in cm) and write them down. Make sure the bike is going to fit and fiind out if they will do a stem change if needed (many upper end shops will whereas places that sell them in the box (Performance) generally won't).
Competitive Cyclist also has a really neat (very detailed) bike measurement calculator. They have 3 ranges from most aggressive (aerodynamic, the "competitive") to the most comfortable ("French") and a middle ground ("Eddy"). I used this and found it helpful. I'm 40, 5'8" and personally prefer the French fit (larger frame in my size range; 53 cm with a 54 cm top tube).
This may be an outstanding time to consider what your goals are. If you are looking to get more competitive, you may want to go with a smaller frame (lighter, and flatter back position in the drops). If you have lower back pain, you may favor going a little bigger, with a somewhat more upright position, and perhaps you'll be more comfortable. I've personally found if I'm in pain, I'm not as fast. I may lose a little in the aero department but I feel like I make it up in stamina, especially as the hours wear on.
(2) Shop around. There are some great deals out there. I purchased a closeout Litespeed Vortex (Douglas) with Ultegra 10 for $2000 American from Colorado Cyclist. Check the "closeouts" and "blowouts" pages for the best deals.
I STRONGLY considered buying a rig from Bikes Direct based upon feedback I saw around the web. The seem to give you a ton of value. I personally don't care for aluminum frames, however, so that was the deciding factor (and I didn't care for their carbon).
The neat thing about using these types of places is that you can perhaps ride something that everyone else DOESN'T. In the US, everyone is on a Specialized, Giant, or Trek. They are all very good brands, but I don't want to ride everyone else's bike. Right now I have a Look KX Light and the Vortex and love them both. They are also kind of conversation pieces as they are unique in this area.
Being Canadian you may favor Cervelo. They are great bikes and if there is a problem (warranty; I believe lifetime on the frame) dealers should be easy to find. I really considered one but they don't fit me quite as well and I found the best deal on the Vortex.
Lotsa luck. Hope you find what you are looking for.
