Track Identification needed

I have been trying to find out the source of some code 250 Aluminum flex track that my brother gave me in exchange for some code 332 aluminum flex track he needed. the under side of the ties read MAR Tech made in Canada PHS Rail. I have done google searches for MAR Tex Canada and PHS Rail and can not find anything. Does anyone know about this flex track as its really great and I would like to get some more if its still available. Dan
