The McCartneys are the latest in a string of celebrities to campaign against the hunt, including Bardot, the Dalai Lama, singer Charles Aznavour, Kim Bassinger, Juliette Binoche and Richard Dean Anderson.
Canadian officials said their visit would have no impact on the hunt, but its start this year is in doubt because of dangerously thin ice.
Canada banned the killing of seals less than 12 days old and breeding adults in 1987 amid criticisms and threats of European boycotts that pushed the industry to the brink of collapse.
After that protests eased, but Canada sparked the wrath of activists in 2003 by approving a three-year cull of some 975,000 seals after estimating their population had ballooned to 5.9 million — nearly triple the number in the 1970s.
This coincided with the opening of new markets in China and Russia.
