MOST LABS FOUND THROUGH TIPS

York Regional Police Chief Armand La Barge said the force discovers most
marijuana grow labs through tips from the public.

In fact, he said the heat from inside a grow operation is, "enough to melt
the snow off of the roof in the winter," making them easy to spot.

Here are other signs the chief said may mean a house in your neighbourhood
is a marijuana grow op;

. lights on 24 hours a day:

. covered windows;

. heavy condensation on windows;

. people coming and going at odd hours and only entering thorough the garage;.
