It might help to indicate where in Canada you are located. Also what brand is the press? The prime source in Canada for the past 20 years for cold mount glass topped presses was the Spraytex Company out of the Toronto area. Their press was a knockdown unit that joined together like you do aluminum moulding with large corner brackets. Since the Spraytex press came apart easily you could easily ship it and obtain a new glass top where you are located. The other most common one was made with welded corners by the Corona company in Seattle.
