Since you now have a number of possibilities to consider, I will not attempt to attach my vote to any one of the above. I mount all paper products with cold/pressure sensitive adhesives and they work very well, never a problem. However, not so much with canvas. It will stick and stay for a few months, but that's about all you can rely on. Heat activated dry mount adhesives seem to work very well, according to some of my canvas customers who have tried that procedure. The heat tends to melt the adhesive to some extent, therefore adhering much better to the canvas texture.
Therefore, although I cannot tell you what you should use, I can definitely tell you what you should not to use, and that would be the cold/pressure sensitive mounting adhesive.
