Keeanh--Girl, you know I'll stockpile US goods here for you until you're next in town!
Okay--so why don't we just cross the border with our strollers in the trunk? Well, the burden of proof IS on them, but CBSA can make your life absolutely miserable if you get a seizure on your record. I know from experience, and I wasn't even doing anything wrong.. I brought something back about 5 years ago (they were WAY more strict) and I declared it. It was something that was refurbished, and my invoice didn't have a price on it. I knew the price, and I declared it as such. They looked it up on the website, and pulled the non-refurbished version...and said my $200 item was $300, and I was lying. I got reported as a smuggler, and had a seizure on my permanent record.
Of course, because I wasn't lying, I was able to appeal and get a copy of the receipt and mail it in. But even after that, for YEARS, there was a seizure report and warning on the cashier system inside. Five years, in fact. I think it cleared in 2010, because I stopped getting harassed at the border.
You can bring about $300-$500 worth of stuff, PLUS your groceries, into Canada without them so much as batting an eyelash. Why lie? Seriously--why bother? Generally, you're only stuck paying taxes (12%)..sometimes there's duty. If 1 out of every 5 times you're in for tax, and you're already saving hundreds or thousands of dollars...WHY lie? It's not worth it--coming from someone who was telling the truth and still put through the wringer.
Of course, I cross twice a week and have since moving to Canada in 2002... so for me to have one problem in that timeframe probably isn't unexpected. Now I have internet on my phone so I pull up my receipts that are missing before crossing.
