It may not be December, but Canada Post is making every day feel like Christmas by delivering millions of packages across the country — and the postal service is warning of more delays.

Canada Post marked its busiest day in history on May 19, delivering a staggering 2.1 million parcels to Canadians across the country.

The company says that's about triple the volume it would normally deliver at this time of year.

The overwhelming volume of packages is causing some problems, however; Canada Post says customers can expect more delays in the coming weeks as the company continues to struggle to keep up with the unprecedented demand.

But it's not just the number of parcels that's resulting in delays — it's what's inside of the packages, too.

Canada Post says that demand for larger household items such as "mini-fridges, patio furniture and barbecues" has increased, and since it takes two people to safely carry these bulkier items, it also takes a little longer to deliver them.

"We understand the importance of these items, especially at this time, and thank Canadians for their patience and understanding," Canada Post said in a statement on Tuesday.

"Our employees are working hard to serve and we'll continue to keep customers updated on our progress."
