Sighting of large triangular craft – in the 90’s

Approximately 27 years ago, in the summer, when I was a teenager; a friend of mine and I both saw a UFO.
I lived approximately and hour north of Toronto, in Ontario, Canada, in a small farming town, population approximately 12,000.
I don’t recall the exact time the sighting happened, but it was late at night or in the early morning hours. It was certainly dark outside.
My friend had walked me home, from his house. We were standing across the street from my house, in a residential neighborhood. We were chatting, and saying goodnight.
My neighbourhood was built on a fairly steep hill. The streets ran in and east/west direction, the top of the hill was to the north. My street ran along the bottom of the hill. Looking north from my location, I could see homes up the hill.
I don’t know who saw the UFO first, but I recall looking up the hill, and seeing lights appear in the sky overhead coming in my direction. Before I knew it, the UFO was passing above us. This craft, was massive, at least the size of a football field. It was triangular in shape, it had several lights (I only recall red and yellow, but there may have been more). The bottom of the craft, looked like it was carved metal. Almost like runes are carved.
It’s really hard to judge the distance it was flying at, but I do recall it feeling like it was very close, perhaps around 3000 ft. above us. My biggest recollection of it, was that it was completely silent. It was not moving very quickly, perhaps 30km – 50 km per hour; slowly enough that we were able to get a clear look at it. It passed over us, and then over the streets to our south. We lost sight of it, and both stood in silence for a minute. I know I was feeling very stunned, and very confused. We looked at each other, and both said “what the f@%k was that!”. We compared notes as to what we had just witnessed, and the details were the same. We discussed it in depth for a little while, both agreeing that there was no way that the craft was human made. Oddly enough, though we talked about it several times over the next week or so, I don’t remember discussing it much with him later. We were friends for another three years. I think there was just nothing left to discuss, there was no other explanation than what we had already come to. This craft had to have been a UFO.
My friend and I both thought that this sighting had to have been shared by many other people in our town. Although it was late at night, that there must have been some people still out and about. We expected this to be big news, that it would be reported to the media. I checked the next news paper that was published, and there was no mention of it.
However, it was later that year, that there was a UFO symposium advertised in our town. There was talk about a huge increase in sightings in a triangular area, my town and two others being the points on the triangle if looking at a map of southern Ontario. I attended the symposium, which was interesting, but not especially helpful, except in making my friend and I feel less alone in our experience.
I have had a few other experiences since. One sighting of a light that was stationary initially in the night sky, and then began to move in an infinity pattern. That sighting was also experienced by my Mother. Who, was frightened, demanded that we go in the house, and then refused to discuss it again.
Hopefully I have written a clear enough account here. It’s challenging to remember all the details, so I may have missed some. I really regret not writing down my account and drawing what I had seen immediately after the event. As a youth, I had no clue that memories would fade, even for shocking events.
