It is not so much a matter of Canadian-made Guitars as it is where the wood was grown.
Because of its short/long/short growth cycle most Canadian-made Guitars manufactored from wood harvested in Canada....are considered inferior to those guitars made from wood contracted from the southern-climates...ie. closer to the equater with a long/long/long year cycle.
Much like the pasta spaghetti...the closer to the clime...the better.
