My cat has been missing for 5 nights

[Nat]

He left last Friday morning. As usual. And as usual he would be back by 6 PM to meet me from work. He never did. The weather in Toronto for the past 4 days was terrible, cold nights and heavy rains. I am afraid he is hit by a car and the one who is responsible just took him away.

There is still some tiny hope left. he is 1.5 years old black long-haired cat, with orange eyes. Very active, a real hunter. He is also microchipped.
may be someone will see such a cat, may be he is injured, may be he is just weak. We need him , our house is just an empty garage now without our cat.
This is the Beaches erea, the very east side of Queen street (Toronto)
