Safety in Canada is not usually a problem. Overall crime rates in Canadian cities remain low compared to most similar sized urban areas in the United States and much of the rest of the world. Violent crime needn't worry the average traveler, as it is generally confined to particular neighbourhoods and is rarely a random crime. Police in Canada are almost always hardworking, honest, and trustworthy individuals. If you ever encounter any problems during your stay, approaching a police officer is a good idea.
Visitors to large cities should be aware that parked cars are sometimes targeted for opportunistic smash-and-grab thefts, so try to avoid leaving any possessions in open view. Due to the high incidence of such crimes, motorists in Montreal and some other jurisdictions can be fined for leaving their car doors unlocked or for leaving valuables in view.
Canada is very prone to winter storms, including ice storms and blizzards. Reduce speed, be conscious of other drivers, and pay attention is probably a good idea. If you are unfamiliar with winter driving and choose to visit Canada during the winter months, consider using another mode of transportation to travel within the country. If you are touring on foot, it is best to bundle up as much as possible in layers with heavy socks, thermal underwear and gloves.
Marijuana use and Khat is illegal in Canada. Canada has no constitutional rights relating to gun ownership. Possession, purchase, and use of any firearms requires proper licenses for the weapons and the user, and is subject to federal laws. Mace and pepper spray is also illegal unless sold specifically for use against animals.
The health care system is one of the best on the planet, and is very effective and widely accessible. Visitors should note that, while Canada has universal health care for residents, health care is not free for visitors, therefore it is important to make sure you are covered by your insurance while traveling in Canada.
