Oshawa is lacking in Tea shops (especially those that sell loose-leaf) and the "Cup of Tea Bakery and Cafe" is only one of two in the area. A fair selection of teas for sale and assorted tea ware. The main attraction seems to be the baked goods. Three people ahead of me in line all bought some of the gluten free and organic treats such as squares, cookies and cupcakes. There isn't any room inside to sit down and enjoy a cup, but you can get any of their assorted teas/coffees to go.
(Side note) I was a little surprised at first when I was handed a cup of Rooibos tea with the leaves just floating in the compostable cup . When the employee put the lid on, it all made sense. I have never seen this before, but the lid contains a filter and it worked perfectly. The leaves got to steep and none came through while drinking.
