Have you used the search - there's a lot posted on passing emissions testing, including in the Canadian forum. You need more info posted on your setup. In particular - are you using a cat(s)? And what were your numbers on all measures (HC, CO, NOx), as they provide clues as to where your tune or emissions equipment are failing.

Things that could cause that:
Not hot enough cat during test.
Nasty oil.
Poor spark plugs/wires/coils.
Air pump not working correctly.
Bad cat.
Engine ported too much.
Denatured alcohol helps bring HCs down. You can always try that there are many threads about it.
