Apple Weather uses your precise location if you allow it to, meaning it knows your location down to a meter, network and positioning issues etc notwithstanding. It doesn't have to guess your weather based on "Toronto", it knows your GPS coordinates. There is no technical limitation here, as I outlined in a separate comment thread [0], other apps already give you weather data and predictions with this granularity.

Meanwhile the Google Weather app constantly insists I live in Frankfurt while I'm in Warsaw.

Fur Deutschland...

On a serious note I'm dealing with this as well - I live in a middle-sized city in the centre of the country, not in Kraków!

The technical limitation would be on the weather data size: what is the granularity/resolution of the radar data on where rain is actually falling?

Further: what is the geography of the area, and how does that effect things as well? Toronto specifically has (a) all sort of heat island effects, (b) certain areas are effected by the lake and how weather systems cross it at certain angles, and (c) has enough of an elevation change going north of the lake (e.g., Niagara Escarpment) that there are a few ˚C change in temperature that makes the differences between snow and rain.

This exists on a smaller scale too. I'm in a town perfectly covered by a small hill range from the direction the wind is coming 99% of the time. This means almost every forecast for rain is valid 3km south and north of me, but not in the town itself.
