The McLaughlin automobile company began life in 1876^[1] as the McLaughlin Carriage Company, a blacksmith's shop in the village of Enniskillen, located 20 kilometres (12 mi) north east of Oshawa, Ontario, Canada. The company began making horse-drawn carriages in the mid 19th Century, moving to Oshawa, Ontario in 1876. The most successful of their time, producing more than 25,000 carriages a year,^[2] the company grossed $1,000,000.00 1898 incorporated as the McLaughlin Carriage Company of Canada Limited. in 1901. By 1915, the company was making one carriage every ten minutes.^[3]

Under the guidance of "Colonel" Sam McLaughlin as President in 1907, the company began the manufacture of automobiles, eventually forming an alliance for 15 years with the Exchange of $500,000.00 of Buick stock for $500.000.00 of McLaughlin Stock with William C. Durant. Durant had acquired the Buick Motor Company that later would become General Motors Company, a holding company.

During their first few years of operation, the automobiles were known as "McLaughlins". The name was changed to "McLaughlin-Buick" when sales dropped, and returned to "McLaughlin" until 1915 when Chevrolet Motor Company of Canada Limited, owned by McLaughlin, merged both his companies to become General Motors of Canada Limited and allied in 1919 with the Corporation obtaining $10,000,000.00 to build Walkerville plant an establish Canadian Products.. The "McLaughlin" name was eventually dropped altogether, leaving the "Buick" marque still in use today. Until 1914, the cars were finished with the same paints and varnishes used on carriages. This meant each vehicle required up to fifteen coats of paint. McLauglin revolutionized the industry^{[citation needed]} with their painting process.
