We actually have little information on the skill level of those Haitians. I'd like to see some reporting on that.

Unlike the Syrian refugees who were mostly uneducated, I suspect that those Haitians who ended up  in the US probably had more education than average. As in most poor countries, there is in fact a highly educated Haitian upper class.

I don't think there is a low income housing problem in Montreal as there is in Toronto or Vancouver for average families, although there is for large families, e.g. Syrians with more than 4 or 5 children.
