Erick,
Which is the old (20%) road, and which is the new (18%) road? Côte-à-Godin, or Route de Port?

I cycled up this 18% road in 2002, and only managed by (1) weaving; (2) stopping for a break every minute or so; and (3) pushing my bike a lot! I am not sure I would be able to make it now that I am a little older, a little heavier, and a little more cautious!
