Defender Industries. I don't know if they ship to Canada
. I would stick with marine

is what makes makes electrical systems on boats unreliable more than anything else. Also, be sure to stick to ABYC standards with your electrical system
or some equivalent classification. I don't know what Canada
has for yacht electrical standards.
