Information from Health Canada 
Health Canada has reminded Canadians that garage sales now face the same responsibilities as legitimate retailers when it comes to screening for banned or unsafe products. Everyone holding a garage sale in Canada is legally responsible for ensuring products sold or even given away, whether new or used, are safe and meet current safety standards. According to the Health Canada website, a garage sale is effectively breaking the law if it includes lawn darts, corded  blinds, broken toys, toys with powerful magnets, hockey, helmets, tiki torches and any product that has been the subject of a recall.
Healthy Lawn: Many good gardeners consider it a waste of time and energy to bag their lawn clippings for the garbage. More important than a meticulous-looking lawn is a healthy lawn, and grass clippings make a great natural fertilizer.
