Great question — answering as the UphillTech team:
According to Canadian Food Inspection Agency in the section Products allowed into Canada from countries other than the United States you are Ok bringing herbs, spices and tea, so your bags and leaves of tea should not be a problem. About candies it says you can bring up to 20Kg, which should also be enough, right? Be advised that these requirements may be adjusted at any time because pest and disease situations are constantly changing. Even though some items are allowed into Canada, you still must declare them on your declaration form, and some provincies have their own regulations. I suggest you take a look at the link I provided and read all information.
