The article above shows a good crating method, unfortunately there will be no inexpensive shipping cost. The worst part is you are going to be to big for many companies. Fedex UPS and the postal service will all allow HUGE packages to ship INTO Canada, but shipping out is a different set of rules all together. When I bought my Kangaroo it came up here UPS, when I sent it back, it was to big in the exact same box, UPS wouldn't take it. Fortunately the buyer was in upstate new york and was willing to drive into toronto to pick it up as he had family there so I only had to ship it from Red Deer, Alberta to Toronto. I used Greyhound, they will accept a large package, unfortunately if you ship it cross border you pay a $40 broker fee right off the top, and they of course weigh it by dimensions, so even if your package is only 50 pounds, the dimensional weight is going to be upwards of 200 pounds. Chances are good this will cost you over $300. I shipped a BVM F16 to California this method and the shipping cost on Greyhound was $360. Forward air unfortunately has only one hub in Canada and that is toronto. I really think your best bet would be to crate it, and drive it over the border if you can afford the time, then ship it from the closest place you can get to in the US. You could also try calling PBB Global Logistics, they have a shipping center, and they will search for the best price and method to ship for you. If somebody knows a cheaper way to ship into the US, please let me know as well, I ship guitars down there all the time and the average guitar costs me $77 to ship into the USA.
