Every electrical device or component must be certified by the
	Canadian Standards Association (or recognized equivalent) before
	it can be sold in Canada.  Implicit in this is that all wiring
	must be done with CSA-approved materials.  They perform testing
	similar to the UL (a bit more stringent), except that CSA (or
	recognized equivalent) approval is required by law.

	Again, like the UL, if a fire was caused by non-CSA-approved
	equipment, your insurance company may not have to pay the
	claim.

	Note: strictly speaking, there usually is a legal way around
	the lack of a CSA sticker.  In some cases (eg: Ontario), a
	local hydro inspection prior to purchase, or prior to use, is
	acceptable.  The hydro inspector will affix a "hydro sticker"
	to the unit, which is as good as CSA approval.  But it costs
	money - last I knew, $75 per unit inspected.

	ULC (Underwriters Laboratory of Canada) is an independent
	organization that, amongst other things, undertakes the
	quarterly inspection of manufacturer's to ensure continued
	compliance of UL Listed/Recognized products to Agency reports
	and safety standards. This work is done under contract to UL
	Inc (Follow-up Services Division). They are not a branch or
	subsidiary of UL.
