Wawak has these -

If you look at the bottom of the page on the Wawak site, you can change the region to Canada under where it says to request a catalog - it says to choose region US or Canada.
They have other brands of wax tailors chalk too!
I like Wawak - I order from them all the time. Great Customer service!
