Question about kilts and freemasons

[Singlemalt]

I am not a mason and so claim no special insight but I know there is a subset of masonry called the Scottish Rite. It is very active here in Canada with a big impressive building in Hamilton where lots of kilts are seen going in and out. I am sure there must be someone on the forum who can tell us the connection between Freemason's and Scotland which led to this.
