Tins/Cans aren't made from tin and haven't been for years. Nowadays they're almost always steel. Tin taints the flavour but is also poisonous, but it does last longer than steel in damp environments as it doesn't rust. If the can does contain tin, it'll be lined internally with plastic to protect the food.
Anyway, Leah's right, all metallic containers do taint the flavour which is why you should never store food wrapped in tin foil (which is made from aluminium, slightly less poisonous but a lot cheaper than tin). Also why the Chinese use wooden cutlery/utensils.
Next time your syrup can is almost empty, use a spoon to scrape it out and lick the spoon, you'll soon see what she means. It's foul.
