Pricey, but an option: DeWalt Step Ladder
I have this one in the shop. I can carry it in the shop truck but sometimes I take my car and it is just 5in to long to fit in the trunk. The one I use is a featherlite multi-ladder similar to the little giant. It's small enough to fit in my car, it go higher than the DeWalt and I can climb on both sides. They have a model listed for 375lbs on their website, but when I called them they told me it was changed to 300lbs like the one I already have.
I've found a local ladder manufacturer Accueil - Echellex and theirs are rated for 330lbs. But they are asking 650$cnd compared to 480$cnd for the featherlite. For the 30lbs difference, I don't think it justify the 170$ difference. I did not really found a retailler that carry a 1AA multi-ladder in Canada either.
