Sarnia vs Toulouse

Informations

Sarnia is a city in Southwestern Ontario, Canada, with a 2016 population of 71,594. It is the largest city on Lake Huron and in Lambton County. Sarnia is located on the eastern bank of the junction between the Upper and Lower Great Lakes where Lake Huron flows into the St. Clair River, which forms the Canada–United States border, directly across from Port Huron, Michigan. The site's natural harbour first attracted the French explorer La Salle. He named the site "The Rapids" on 23 August 1679, when he had horses and men pull his 45-ton barque Le Griffon north against the nearly four-knot current of the St. Clair River.This was the first time that a vessel other than a canoe or other oar-powered vessel had sailed into Lake Huron, and La Salle's voyage was germinal in the development of commercial shipping on the Great Lakes. Located in the natural harbour, the Sarnia port remains an important centre for lake freighters and oceangoing ships carrying cargoes of grain and petroleum products. The natural port and the salt caverns that exist in the surrounding areas, together with the oil discovered in nearby Oil Springs in 1858, led to the dramatic growth of the petroleum industry in this area.

Because Oil Springs was the first place in Canada and North America to drill commercially for oil, the knowledge that was acquired there resulted in oil drillers from Sarnia travelling the world teaching other enterprises and nations how to drill for oil.The complex of refining and chemical companies is called Chemical Valley and located south of downtown Sarnia. In 2011 the city had the highest level of particulates air pollution of any Canadian city, but it has since dropped to rank 30th in this hazard. About 60 percent of the particulate matter comes from industries and polluters in the neighbouring United States.Lake Huron is cooler than the air in summer and warmer than the air in winter; therefore, it moderates Sarnia's humid continental climate, making temperature extremes of hot and cold less evident. In the winter, Sarnia occasionally experiences lake-effect snow from Arctic air blowing across the warmer waters of Lake Huron and condensing to form snow squalls over land.

Toulouse ( too-LOOZ, French: [tuluz] (listen); Occitan: Tolosa [tuˈluzɔ]; Latin: Tolosa [tɔˈloːsa]) is the capital of the French department of Haute-Garonne and of the region of Occitanie. The city is on the banks of the River Garonne, 150 kilometres (93 miles) from the Mediterranean Sea, 230 km (143 mi) from the Atlantic Ocean and 680 km (420 mi) from Paris. It is the fourth-largest city in France, with 479,553 inhabitants within its municipal boundaries (as of January 2017), and 1,360,829 inhabitants within its wider metropolitan area (also as of January 2017), after Paris, Lyon and Marseille, and ahead of Lille and Bordeaux. Toulouse is the centre of the European aerospace industry, with the headquarters of Airbus (formerly EADS), the SPOT satellite system, ATR and the Aerospace Valley. It also hosts the European headquarters of Intel and CNES's Toulouse Space Centre (CST), the largest space centre in Europe. Thales Alenia Space, ATR, SAFRAN, Liebherr-Aerospace and Airbus Defence and Space also have a significant presence in Toulouse. The University of Toulouse is one of the oldest in Europe (founded in 1229) and, with more than 103,000 students, it is the fourth-largest university campus in France, after the universities of Paris, Lyon and Lille.

The air route between Toulouse–Blagnac and the Paris airports is the busiest in France, transporting 3.2 million passengers in 2019. According to the rankings of L'Express and Challenges, Toulouse is the most dynamic French city.Founded by the Romans, the city was the capital of the Visigothic Kingdom in the 5th century and the capital of the province of Languedoc in the Late Middle Ages and early modern period (provinces were abolished during the French Revolution), making it the unofficial capital of the cultural region of Occitania (Southern France). It is now the capital of the Occitanie region, the second largest region in Metropolitan France. Toulouse counts three UNESCO World Heritage Sites: the Canal du Midi (designated in 1996 and shared with other cities), and the Basilica of St. Sernin, the largest remaining Romanesque building in Europe, designated in 1998 along with the former hospital Hôtel-Dieu Saint-Jacques because of their significance to the Santiago de Compostela pilgrimage route. The city's unique architecture made of pinkish terracotta bricks has earned Toulouse the nickname La Ville Rose ("The Pink City").
