Ontario recently released an online Guide to eating sport fish outlining the safe limits of fish from hundreds of different lakes and rivers, and have now taken it one step further by integrating their data with Google Maps.
Fish can be an important part of a healthy diet, because they are high in quality protein and low in saturated fat, but in some cases care must be taken because of contaminant levels in the fish.
Anglers can use the guide to identify species and angling destinations with lower contaminant levels. The 2011-2012 edition includes advice for sport fish from more than 1,950 lakes, rivers and streams around the province.
As it turns out the northern pike in the Toronto Harbour and Toronto Islands are actually quite safe to eat, with a suggested limit of 8 meals per month.
