Yes a 1 year old can have maple syrup but don't give them too much at a time because it can be too rich for them and may cause choking.
However I used to make pancakes for my son when he was 1 year old and fed him bite sized pieces of the pancake and he would not eat it without a bit of maple syrup on the pancake.
Your 1 year old should not get sick from the maple syrup but just don't pour a bunch of maple syrup on the pancake and your 1 year old can safely eat it.
Just cut the pancake up into finger sized foods so that the 1 year old can eat it more safely and not choke on the food.
Some people including doctors don't recommend feeding a baby maple syrup or a 1 year old maple syrup due to the risk of getting sick from it but my 1 year old lived and he's now 13 years old and still loves eating pancakes.
But now he loves to pour a lot of maple syrup on the pancakes.
