In St. Catharines the door over the car is an overhead door, which is the trade's own word for it and the one people here use, and Protech Garage Doors supplies, installs and repairs them, residential and commercial, along with the openers that lift them, from its Mississauga branch about 100 km away by the QEW and the 406. There is no St. Catharines shop. Most of the city's doors were hung between 1961 and 1980, and that sets the work more than anything else. Send the contact form or email info@protechgarage.ca.
Why it is an overhead door here
Owen Dautrick filed for a patent on an upward-acting garage door in 1919 and got it on 1922-02-28; he and C.G. Johnson filed a second one in 1921, and by January 1923 the Detroit press was calling their firm The Overhead Door Company. The name stuck to the thing: a door that goes up over the car instead of swinging out into the driveway. In a city that made its living from engine plants and canal-side mills the trade word is the one that survived, and more people in St. Catharines search for an overhead door than for garage door repair. So Protech uses the local word here. The door it means is a sectional steel or wood door on tracks, the same residential door or commercial door that goes by garage door elsewhere.
A 1961 to 1980 city
On 1961-01-01 St. Catharines took in Grantham Township, Merritton and Port Dalhousie and more than doubled, to 84,472 people. The subdivisions that filled Grantham in the twenty years after are the city's housing: the 2021 Census counts 58,905 occupied dwellings, and 22,675 of them, 38.5 per cent, were built from 1961 to 1980, the largest share for that band of the seven Hamilton and Niagara municipalities Protech covers. Another 19,160 are from 1960 or before. Only 1,655 were built in the five years to 2021, the lowest new-build share of the seven. So the St. Catharines overhead door is usually forty-five to sixty-five years old, or a replacement of one, on an attached garage on a 1960s or 1970s street, and its opener is on its second or third life.
The opener goes first because it wears out on a schedule the house does not, and a 1970s garage under a bedroom is where the belt drive earns its place. Protech installs LiftMaster, Chamberlain and Genie openers, and the opener repair page covers the motor-runs-door-stays fault that is a gear kit and a small bill. When the door is the problem, the doors come from Garaga, Amarr and Stanley, an insulated steel door is the sensible choice on any attached garage in a city that takes the lake wind, and the Build Your Door designer shows the panel and colour on a Grantham split-level before anyone orders.
GM left Ontario Street and stayed on Glendale Avenue
The plant at Ontario Street opened in 1901 as McKinnon Dash and Metal Works, went to General Motors in 1929, and closed in 2010; demolition began in 2016 and the site is a contaminated brownfield with lead, trichloroethylene, benzene and PCBs in it. Employment across GM's two St. Catharines plants had peaked near 9,700 around 1980. The Glendale Avenue plant is the one that stayed: on 2026-04-29 GM announced 691 million dollars to build its sixth-generation V8 there. Between the two, along the Welland Canal corridor and through Merritton, where the Lybster Mill dates from 1860, is the industrial stock whose overhead doors are dock doors and shop doors. Protech services and replaces those and their commercial openers on a booked visit.
Port Dalhousie and the heritage permit
Port Dalhousie was the Lake Ontario end of the first three Welland Canals, and its commercial core on Lakeport Road, Lock Street and Hogan's Alley, the residential streets along Main Street, Dalhousie Avenue and Bayview Avenue, the 1820s cemetery and the entry locks are a Heritage Conservation District under City By-law 2003-63. The City says an owner in the district "may need to purchase a heritage permit before beginning construction or renovation work." An overhead door facing the street on a Port Dalhousie house is exactly the kind of change to ask about before ordering it in a colour, and the answer is the City's to give.
Getting a van to St. Catharines
The run from Bonhill Road is the QEW through Hamilton and along the lake, then the 406 or the Ontario Street exit, about 100 km by road. Repairs are booked same day, and at 100 km the window is longer than it is nearer the branch; no arrival time is promised. Say the street and whether it is Port Dalhousie, Merritton, the Grantham streets or the canal side, and for a door off its track do not run it until someone is there.
Permits in St. Catharines
The City of St. Catharines lists garages, attached or detached, and carports among the projects that need a building permit, along with accessory buildings over 15 square metres and any enlarging of a door opening. A replacement door in the existing opening is not on the list. For a new detached garage on a Merritton lot, a widened opening, or anything in the Port Dalhousie district, the City's Citizens First desk answers at CitizensFirst@stcatharines.ca.
Repair or replace, and then the form
A 1972 Grantham door with a stripped opener gear is a repair. The same door with the bottom section rusted through from lake-side salt is a replacement, and the spring on it should not be replaced first. A dock door on the canal corridor that has begun to hesitate is a commercial opener booking before it is a door. Protech does not quote a price online. Send the contact form with the street, the door type and what it is doing, or email info@protechgarage.ca for a quote on an overhead door or an opener.

Why overhead door rather than garage door?
Because it is the local word and it comes from the patent. Owen Dautrick filed for an upward-acting garage door in 1919 and got the patent on 1922-02-28, and by January 1923 the Detroit press was calling the firm The Overhead Door Company. In a city that lived off engine plants and canal-side mills the trade word survived, and more people here search for an overhead door than for garage door repair.
My house is in Port Dalhousie. Do I need a heritage permit for a door?
Ask the City, and ask before you order a colour. The Port Dalhousie Heritage Conservation District under City By-law 2003-63 covers the commercial core on Lakeport Road, Lock Street and Hogan Alley, the residential streets along Main, Dalhousie and Bayview, the 1820s cemetery and the entry locks. The City says an owner in the district may need to purchase a heritage permit before construction or renovation work.
Which part of the city should I name when I write?
Port Dalhousie, Merritton, the Grantham streets or the canal side, because they are different exits off a 100 km run and different housing. The Grantham subdivisions built after the 1961 amalgamation are the largest block in the city, 22,675 dwellings from 1961 to 1980, and only 1,655 homes were built in the five years to 2021.
