This place that of which opens from 12pm - 7pm on select days makes it difficult to get to if you are not in the area however if you get the chance to - this is one of the freshest fish markets that I've experienced so far in Ontario that is of comparative quality to the sushi in Japan.
This is a take-out only place and though you pay more, you definitely pay for the quality of the fish which is much worth the try if you have ever been to Japan before and tried the fish there.
Why I say it is good to have that comparison because the freshness you get in Japan in comparison to what you can get here - you will notice the taste of quality to be quite similar. Eating other fancy restaurants paying a premium for what it is may not have you appreciate the sushi to the same degree as when you compare back to Japan.
Very great place to try out if you are a sushi/sashimi/seafood fanatic.
