I think you mean left of centre governments which true right now if this goes through, which it almost certainly will means Saskatchewan and Manitoba and maybe Quebec depending on definition are the only centre-right governments left in Canada.  Off course Ontario next year and Alberta in two years have elections and I suspect at least one of those two will swing rightward considering how poorly Notley and Wynne are doing in the polls.  It's possible each of those two can be re-elected, but both face uphill battles so highly unlikely but not impossible they both win.
