Make an appointment with your veterinarian, and obtain signed International Health Certificate documentation, which you will need to have with you when you cross the border.
Have your veterinarian perform an Equine Infectious Anemia (EIA) test. Only horses with negative EIA results will be permitted to pass from the United States into Canada.
Bring along your horse's documentation. Proof of ownership is required, and you must be able to show that your horse is from the United States. Non-U.S. horses may not be permitted entry into Canada.
Gather documents for any events you may be attending or performing in and show these to the border patrol officials.
Give yourself plenty of time at the border. An inspection could take several hours to complete.
Transporting a horse for sale or for delivery to a Canadian buyer requires the same documentation and veterinary inspection mentioned above.
Call the border entry station ahead of time to find out when the on-site veterinarian will be available. Depending on your horse's condition, it may be subject to a health examination before entry is permitted.
Selling a horse requires the seller to pay Provincial Sales Tax (PST) and Goods and Services Tax (GST). Call ahead for an estimate of these taxes so you are prepared when you reach the border.
Obtain a tax receipt in case your buyer is required to report it in their records.
