The Canadian Food Inspection Agency says the company is recalling most sizes of Mini-Wheats brown sugar and original frosted cereal sold nationwide.
The country's food safety watchdog says pieces of potentially harmful metal were found in the cereal.
The products have best-before dates between April 1 and Jul. 29, 2013.
The CFIA issued the recall with little fanfare on Oct. 7 and has not reported any injuries since.
Kellogg Canada could not immediately be reached for comment.
