Although most of us have likely grown out of our Happy Meal-buying days, there's nothing Canadians won't do for a little taste of nostalgia. 

That's why people of all ages are purchasing Happy Meals at their neighbourhood Mcdonald's today. 

In honour of the 40th anniversary of the Happy Meal, Mcdonald's has introduced the limited-edition Surprise Happy Meal featuring iconic throwback toys from the past 40 years. 

Some of the beloved retro toys making their return include Space Jam Bugs Bunny, Tamagotchi, My Little Pony and the original Cowboy McNugget.

"Parents tell us how fondly they recall their favourite toys," said Colin Mitchell, McDonald’s Senior Vice President of Global Marketing, in a statement.

"So, unboxing the Surprise Happy Meal together creates a real moment of bonding with their children. We hope these toys are something that they will treasure and remember."

For anyone who needs a little whimsy, McDonald's is doing retro Happy Meal toys for 4 days and their app has 2 for 1 Happy Meals today. 🍔 pic.twitter.com/qnaEhoPPfy

Canadians seem to be extremely excited about the toys, and many of them are choosing a Happy Meal as their lunch for the day. 

I'm debating a McDonald's Happy Meal for lunch so I can get a retro toy. Note that the meal and toy are for me, not my daughter.

Some are even calling their local McD's to ensure they have the toys before heading over. 

Yes, I have called a @McDonalds looking for the new retro Happy Meal toys. (And they say they're getting them tomorrow?)

Satisfied Canadians are sharing photos of their retro toys on social media, and it seems most are making the purchase hoping for a specific retro toy.

I’m in my 30s but I had to get a Happy Meal from @McDonalds for a Retro toy. I wanted the Nuggets and instead got Bugs Bunny, who is cool, don’t get me wrong, but I’m all about the Nuggets. Or Grimace. pic.twitter.com/uhkCJshenS

Some are expressing their disappointment after buying a Happy Meal without a retro toy inside. 

I went to 2 McDonald’s and no retro toys.😩 pic.twitter.com/lcPrf1hZvo

Others are thinking of what toys deserve to make a comeback at this time next year. 

Retro Happy Meal toys that deserve to make a return for McDonald's next anniversary:
-Bionicle Mctoran
-Robo Chi Pets
-Those cruddy Sonic LCD games
-Neopets
-Wowwee Robots
-Those buildable LEGO racecars

That's all I can think of

Many are laughing at themselves for buying a Happy Meal as an adult, but I think it's safe to say that no one is judging.

If McDonald’s thinks I’m going to walk into today and buy my 23 yr old self a happy meal, just for the chance to get the retro tamagotchi toy then they are absolutely right

The retro toy offer is available in more than 90 countries around the world at participating McDonald’s restaurants from November 7 to 11 — that is, if they don't sell out first.
