I shipped Meadowlark Blue Heron 2's in original heavy duty wooden crates, from Northern California to Vancouver, British Columbia. Customs did open them and in the process damaged a very expensive tweeter. The Audiogon buyer in Vancouver was brushed aside by customs folks and we had to split the cost of the repairs. Customs folks routinely open these boxes and are notoriously careless. I won't ship to Canada again.
