In the top picture the leaves appear to be alternate. Assuming a wild plant that, according to my field guide, narrows it down to poison ivy or possibly fragrant sumac (Rhus aromatica). None of the other alternate leaved plants with three leaflets that fit can be vines. The long petiole on the end leaflet of poison ivy is long, the end leaflet on fragrant sumac tapers towards its base. In the ID plant that distinction is rather ambiguous. Another difference is that poison ivy produces aerial rootlets whereas fragrant sumac does not. Since we can't see the older stems in the pictures that's something you could look for lower down on the stem.

Cissus rhombifolia would not be growing wild in Quebec. Edited to add there is a Cissus incisa but it doesn't look like a match and the range given in my field guide does not go as far north as Quebec. It differs from poison ivy also in not having aerial roots.
