You are looking for a registered trade mark. The first thing you need
to do is design the trade mark you would like to use. Prepare it in a
photo ready black on white format, you will need it for your
application. Then contact a company that specializes in trade mark
applications. Out here in Alberta, I used “Arvic Search”. They might
have an office in Toronto. Get an application from them and prepare
it. You will need to submit it to them with a retainer. They will
search your trade mark throughout north America. If it is available,
you can apply for it…if not, it is back to the design board again.
Once you have an accepted trade mark, it is listed, and they allow
time for anyone to contest it. If no one does, it is yours. I got
mine years ago, but if my memory serves me right, the process took
close to a year, and I think was about $800 CDN. Once you have your
mark, you can have to have a punch made and start marking your
pieces. In Canada, you are not supposed to apply a quality stamp
unless it is accompanied by a registered trade stamp as well.
