The Great One now owes a great deal of gratitude toward cops in Canada ... 'cause police in Ontario say they've recovered a bunch of Wayne Gretzky's memorabilia after it was stolen from his dad's home in the summer.
Cops say back in August 2020 ... Gretzky family members reported a bunch of Wayne's game-worn items and awards had been jacked from the home of his 82-year-old father, Walter Gretzky.
Police say memorabilia that was taken included game-used sticks, jerseys, gloves, pants and even a Player of the Year award.
But, good news .
