Tim Hortons is officially delaying Roll Up The Rim 2020 due to the outbreak of coronavirus.

The Canadian coffee giant announced on Friday that it will be holding off on the distribution of the 1.8 million reusable cups that it planned to give away on March 10.

Similarly, Tim Hortons will follow in Starbucks' footsteps and no longer accept reusable cups — a major blow, considering that this year's Roll Up the Rim contest was designed to place emphasis on sustainability.

Any customer that brings a reusable cup into a Tim Hortons location will still receive three digital rolls, but will be served their beverage in a recyclable paper cup instead.

The news release says, "We will continue to be prudent and never compromise on doing the right thing for our guests, team members and the communities we live and work in."

"As information and guidance from public health officials changes, we will reassess and change our procedures and protocols accordingly."

Canadian coffee chain Second Cup has also stopped accepting reusable mugs for the time being.

If you do show a reusable mug in-store, we’re still happy to honour our 20-cent discount, but beverages will be served in paper cups. The health and well-being of our employees and our customers remains our highest priority and we appreciate your understanding. (2/2)

As of March 5, there are 45 confirmed coronavirus cases in Canada; Ontario also has four more presumptive cases, and B.C. and Alberta both have a presumptive case each — bringing the grand total to 51 coronavirus cases.
