Exterior weeping tiles usually fail 15-25yrs into their life span due to blockage from debris in the line, tree roots, or iron in the water (which is common in Ontario).
There are many factors to take into consideration before you decide to install/ replace the weeping tile. Decks, walkways, tree roots, and gas/waterlines are all factors that have to be taken into consideration. Do permits have to be pulled? Is there ample room for exactors to get in?
