Fascinating site, Roger, but I think the OP was asking about Highland immigrants, not Ulster-Scots. Like Rathdown I am hoping he can refer us to his sources. We know from inventories that the Northwest Company Highland employees in the late 18C, and employees of the Hudson's Bay Company at earlier dates, did wear Balmorals and some woolen goods from Scotland. The HBC's old "The Beaver" magazine published hundreds of articles on the culture, clothing and habits of its employees and others in Canada and might make a good resource for JPI. No kilts, mind you.
