Greetings Blu,
Why not take a drive to Barrie and visit Burnetts and Struth. (http://www.burnetts-struth.com/sale.html#MensKilts)
They have a nice selection of kilts on the rack - probably in your size, and the prices are reasonable. These are not lightweight imitations - they are really nice. They are mostly 13oz as far as I could see.

Cheers
