I have seen them at all of the above and at a few Loblaws locations too.
However unless you have some kind of sentimental connection with Tajin I recommend buying the ingredients from Kensington and making your own mixture. It's so much better.
Can you recall which Loblaws stores Basileater!?!? I am in the west end and am curious to know if anything is closer than Pacific and Dundas......Thanks!
