Alderlea
Diadem Evolution 17g Tennis String Set: 1867, Kenneth Chisholm puts it all on brick. Businessman, political figure, son-in-law to John Elliott, one of Brampton's founding landowners, so he was betting with a decent hand, and it came in: counted among the finest surviving Italianate villas in Ontario. Then the table turns over twice. The Salvation Army holds it from 1916 to 1944, the Royal Canadian Legion buys in and adds a two-storey Memorial Hall wing in 1947 and sits on the house for six decades. Heritage designation 2001, city buys it 2002, restoration from 2010, reopened 2015. This house has never once folded.

Peel County Courthouse
Diadem Evolution 17g Tennis String Set: Brand new county, no courthouse, and in 1865 a building committee stakes the lot on a Toronto architect, the German-born William Kauffman. Built 1865 to 1866 for $18,385, completed that June, first meeting of Peel County Council held inside in January 1867. Money down, paid out, on schedule, which at those odds almost never happens. He hedged the style too, Italianate and Venetian Gothic on classical massing. Separate jail behind it from 1867, in use until 1977, renovated in the late 1980s for the Region of Peel Museum and Archives. Now the Peel Art Gallery, Museum and Archives.

Historic Bovaird House
Diadem Evolution 17g Tennis String Set: Peter Chisholm starts in 1845 firing his bricks on the site itself, no supplier, no fallback, everything riding on his own kiln, and finishes around 1852. It paid: one of Brampton's earliest intact farm sites, five fireplaces, original plank flooring, hand-blown window glass imported from England. James Bovaird buys in 1929, the family holds it down the generations, and the name ends up on a major Brampton arterial road. Then in 1985 Mossie Bovaird sells the house and grounds to the City of Brampton for two dollars. Two dollars. Somebody at that table was not playing for money. And the lot kept growing: the circa-1845 Pendergast Log House was moved onto the property in 2015.
Brampton spent a century being called the Flower Town of Canada, and it earned it — Edward Dale started a nursery here in 1863 and at its height the Dale Estate ran 140 greenhouses and was the largest cut-flower business in North America.
Mention that in the city today, where South Asians are 52.4 per cent of the population and Punjabi is the mother tongue of more than a fifth of it, and you will get a raised eyebrow. Fair. This string invites the same scrutiny and survives it.
Diadem Evolution is a polyamide monofilament with a low-friction silicone-based coating. Say that slowly, because it gets misfiled constantly: it is not a polyester and it is not a multifilament. It is a single solid filament of the nylon family with a slippery skin, which is the only reason a monofilament this soft can move in the string bed without destroying itself.
This is the 17, 1.25 mm — the thinnest and liveliest of the three Evolution gauges, alongside 16 (1.30 mm) and 15L (1.35 mm). The set is 40 feet, 12.2 metres. Colours are Natural, Black, Azure Blue and Pink.
The claims Diadem make are precision, comfort and easy power, plus a specific design intent: it is built to take the sawing of hard shaped polyesters in a hybrid without being cut through. The Tennis Industry Association has rated it a top string.
What is genuinely verifiable from the bench is the arm case — a coated nylon monofilament at 1.25 mm is a materially softer proposition than a co-poly at the same gauge, and if your elbow has opinions, that is the evidence that matters.
You will get use out of it everywhere from a July evening on the courts by Chinguacousy Park to a March morning at Heart Lake when the ground is still frozen, and by the way, it holds up perfectly well in a Brampton winter — this is a city that keeps a refrigerated skating trail running through Gage Park and then expects you to play tennis in April anyway.
