Remington R1s are decent. Other good 1911s in the lower (so.. ~$800 but not Norinco low) price range are the STI Spartan and the Ruger SR1911, possibly Rock Island as well. My opinion is Spartan, SR1911, R1 in that order.
Of the $1200-1500ish range 1911s, Colts will probably be the most recommended by most people. I personally would love a Colt for a GI model but refuse to buy a 1911 that costs $1400 and doesn't have front strap checkering. Kimbers are very polarizing with many people loving how nice they look and not having issues with their personal 1911s but many people also hating on their use of MIM and other horror stories they have read on the Internet (despite SIG and Springfield also using MIM). SIG 1911s are typical SIG quality (which is a good thing), and have a lot of unique looking models to choose from. Don't forget Springfield and S&W but they seem to be rather rare in Canada.
To be honest, if you are considering a 1911 in a Kimber/Colt/SIG price range, all things (cost, quality, availability) considered, I would go STI. Springfield and STI are the only 2 1911 brands that I basically never see any haters, and as I said, Springfields are very rare in Canada. Lots of models to choose from by STI as well.
