Boxes declared as "fresh produce" and containing 34 cardboard boxes and plastic bags were inspected by CBSA officials on April 13.
Officers X-rayed one of the bags and noticed inconsistencies.
In the bags, they say they found two fabricated breadfruits made of plaster and painted lime green amidst numerous real breadfruit.
Both of the fake breadfruit were found to contain suspected cocaine.
"This seizure of suspected cocaine demonstrates that our officers will find any and all contraband, no matter what type of concealment method is used," said Goran Vragovic, CBSA Regional Director General for the Greater Toronto Area Region.
The suspected cocaine was turned over to the Royal Canadian Mounted Police.
Breadfruit is a staple in tropical countries and is grown in some 90 countries throughout Southeast Asia, the Caribbean, as well as Central American and African regions.
