In the summer of 2018, Ottawa Macdonald-Cartier International Airport undertakes the reconstruction and expansion of Apron II, a parking area for aircraft. Satisfied with Gatic products for the drainage of its de-icing area, the Ottawa airport opts again for the Gatic UltraSlot brand of steel slot channels for the linear collection of stormwater for its new tarmac.

The contractor, Tomlinson Group, therefore installed more than 300 linear meters of Gatic UltraSlot channels, 225 mm (8.85 in) to 500 mm (19.7 in) in width, in the poured-in-place concrete.
