Andreya, here's a little info. I found, which was just updated on the site. It may help or there may be links there that will give you more info.
I live very close to the New York/Canada Peace Bridge crossing and used to be able to easily go back and forth when traveling with my dogs years ago. All I needed was a valid rabies certificate and a current health certificate. Most times they never even looked at it. But laws are always changing, so be sure to double check.
I can't remember the effective date, but soon a passport will be needed to cross the US/Canadian border. I think for right now a valid driver's license and an original birth certificate is acceptable.
I'll post more this evening after I put the Birds to bed about my experience of traveling long distance with my GW. We took Kady with us on family vacation from NY to Florida and back again. INFO:
For import purposes, the expression "pet bird" means a personally owned and cared for bird, and applies only to species commonly known as "caged" birds such as psittacines, love birds, song birds, toucans, canaries, finches, cardinals, etc. The expression does not apply to pigeons, doves, species of wild or domesticated fowl, or game birds.
It is possible to import personally-owned pet birds under the following conditions:
1. The birds must accompany the owner or in the possession of an immediate family member.
2. The birds must be found to be healthy when inspected at the port of entry.
3. The owner must sign a declaration stating that the birds have been in his/her possession for the (90) ninety-day period preceding the date of importation and have not been in contact with any other birds during that time.
4. The owner must sign a declaration stating that the birds are the owner’s personal pets and are not being imported for the purpose of re-sale.
5. The owner or any member of the family must not have imported birds into Canada under this pet bird provision during the preceding ninety (90) day period.
The necessary certification to clear Customs will be made by filling out the form which is available at Customs. Under the above arrangement, no import permit or quarantine period is required. If these conditions cannot be met, it will be necessary for you to obtain an import permit from the appropriate Canadian Food Inspection Agency regional office in the province into which you will be entering.
The importation of birds into Canada is also subject to the control of the Canadian Wildlife Service (Convention on International Trade in Endangered Species - (CITES)). You may contact them by telephone at 613-997-1840, by facsimile at 613-953-6283 or by email at the following address:
