Target's expansion to Canada was a disaster.
They spent billions purchasing existing Zellers (Canadian department store) locations from Hudsons Bay Company (HBC). Then they spent 100s of millions more renovating them. They leased more locations to open stores. 133 in total. Due to a variety of issues, mainly distribution problems -they tanked, Target Canada declared bankruptcy and had to pay more millions to get out of leases and sell their owned real estate. This all happened in about 5 years.
My favourite part of the story is the HBC took some of the proceeds from the sale of Zellers and bought Saks Fifth Avenue with it. They're recently begun re-opening Zellers
