The impact of McHappyDay extends beyond May 6th. Every day, McDonald’s Canada along with its independent franchisees and guests, help support families with critically sick and injured children staying at Ronald McDonald House across the country through Sparty and Philly at McHappyDay. Yesterday was a day for making an impact and putting smiles on faces, exactly as the name McHappyDay would have one believe. At its heart, McHappyDay is a community event hosted by McDonald's Canada and its local, independent franchisees, driven by a commitment to the neighbourhoods and families they serve. Today, on McHappyDay, $2 from every Big Mac sold goes directly to Ronald McDonald House Charities. Nationally, the duo have been top McHappyDay fundraisers since 2017. McHappyDay® is set to return on Wednesday, May 8, and this year’s edition holds special significance as it marks the 30th McHappyDay event in Canada. Doing good is delicious! Today, McDonald’s Canada is proud to celebrate its 28th McHappyDay, the company’s largest charitable initiative supporting Ronald McDonald House Charities (RMHC) and local children’s charities. Discover what McHappyDay at McDonald's is, when it happens, and how it supports Ronald McDonald House Charities (RMHC). Your complete 2025 guide.
