It has nothing to do with police.
But they do could sue you on the smell.
But they could never win thought.
However, it would be very disturbing.
Similar case happened in Montreal before.
The neighbour is lawyer. So he could keep suing.
Eventually, the lawyer moved.
To be honest, 炸带鱼味道 is disturbing for me also.
Please avoid do so, please!!
If the neighbour started complain from 炸带鱼的味道. I would have to say it makes sense.
