The new, limited-time Spicy McChicken line started with the Spicy Jalapeno McChicken at the end of January and it adds two layers of creamy Jalapeno sauce to the regular McChicken's formula of a breaded chicken patty and lettuce on a sesame seed bun (the Canada McChicken remains largely unchanged from when the sandwich first launched compared to the one in the US, which shrunk to fit the Dollar menu).
On February 12, they added the Spicier Habanero McChicken with a creamy Habenero sauce and coming February 26, 2019 is the Spiciest Ghost Pepper McChicken with a creamy Ghost Pepper sauce.
All three sandwich can be found at McDonald's restaurants in Canada through March 11, 2019, while supplies last.
