I'm a huge chili head and I like it HOT. Have you been to the hot sauce store on Danforth (The Fifth Taste I think it's called)? They let you sample anything you want. It's awesome!
My new favorite is Blair's Pure Death. The flavour is the freshest and tasiest I've ever had. I just wish it was a little hotter. It's made with Naga Jalokia but it's watered down with Habaneros. I was scared to try it, but it's actually very mild. The flavour is almost like fresh tomato salsa, but it only has four ingredients: Orange Habaneros, Naga Jolokia, Vinegar and Baked Hawaiian Red Salt. The colour is gorgeous, super bright orange.
If you like chipotle, then you have to try Hula Girl. It's won tons of awards:
