The bird flu has been a problem for weeks in flocks in Washington and Oregon states.
A CFIA statement says it is taking steps to protect Canadian poultry flocks from a highly virulent strain of the bird flu found in California, Idaho, Oregon and Washington.
The action means that travellers are not allowed to bring back any poultry products that aren't fully cooked.
Canadians shopping in the U.S. are also restricted from bringing back live birds, eggs, egg whites, feathers, poultry manure or lab material containing poultry.
The CFIA says live pet birds may be brought into Canada with certification from the U.S. Department of Agricultural.
