In 1906 this firm was making electric motors between 15 and 60 HP. There are somewhat similarly named companies that operated before and after 1906 in Toronto and Hamilton. More research is required to determine the connections, if any, between them.

In 1895 the Toronto and Hamilton Electric Co. purchased the assets of the then-insolvent Kay Electric Works. In 1906, Toronto and Hamilton Electric Co. and Kay Electric Dynamo & Motor Co., Ltd. were operating simultaneously—the former in Hamilton and the latter in Toronto.

  Toronto and Hamilton Electric Company

  The Toronto and Hamilton Electric Company have carried on business in the manufacture of electrical machinery since the year 1895, when they purchased from the assignee the good will and plant of the insolvent Kay Electric Works, which was then doing business on James street north. Finding these premises too small and unsuited for the demands of their business, this firm was successful in securing possession of their present shop situate at 99-103 McNab street north, a location which commends itself on account of its central position in the city and at the same time its ready accessibility from both railroads.

  The shop consists of a two-storey building 30x120 feet, so situated that light is obtained on both sides, while the upper storey has the additional advantage of sky-lights. A large yard permits of ready access to the building for loading and unloading and gives facilities for storing of such material as can be left, more or less, exposed to the weather.

  Electric motive power is used throughout the shop, while a 40 h.p. boiler in the boiler house to the rear affords a means of heating the shop and provides steam when required for testing purposes.

  The machinery found in the building is of the latest type and improved patterns, including engine lathes, drills, planers, shapers, milling machines, boring mills, automatic notching and other power presses, circular and other shears. For the easy handling of heavy work the shop is equipped with geared travellers by means of which pieces of work may be readily lifted and transferred from one machine to another or from one part of the floor to another.

  The winding department is equipped with the usual dipping vats for the insulation of the form wound coils and completed armature and ovens for the ready drying of the same under any desired safe temperature.

  The firm is composed of Messr. H. E. Job and Robert Lynch. The former is a graduate of the School of Practical Science, Toronto, and Mr. Lynch has a had a thorough training in the mechanical side of the business.

  The firm are prepared to supply a line of multipolar direct current machinery both of the belted type in sizes from 2½ k.w. to 50 k.w. and the smaller sizes of direct connected units. They are also getting out a multipolar motor of the wall and ceiling type, besides the old bipolar type which is still used where a small, cheaper machines is called for.
