I'm not sure what their definition of "Starting a business" is though, since technically in Canada all you need for that is a GST number, which you can apply for online for free and comes in the mail as soon as they can get it to you. You get a temporary number that you can use prior to that.
Trade is about right though, especially from the US. Where this free trade that we're supposed to have is I have no idea.
Starting some sort of limited liability company that is its own legal entity, is my guess.
If you are Canadian and want to start a business, you can find everything you need on starting (and running) a corporation here: http://www.ic.gc.ca/cgi-bin/sc_mrksv/corpdir/corpFiling/regi...
If you buy a USD $2500 computer you can't deduct the expense immediately. Or if you just buy a printer and that plus the computer you use the printer with is more than the limit of around $2000, you can't deduct it from your taxes immediately.
It's true that the paperwork for starting a business is pretty quick and easy. But for a LLC or Corp. type of business structure you need to put a minimum of DKK 125K (about USD $25K) in the business.
