Is this hawthorn or crab-apple?

    There are a row of street trees on the south side of Euclid Ave in Collingwood Community.

    The leaf edge have serration on the upper half. I cannot find thorn!? Thanks.

    You didn't say where on Euclid, but the only Crataegus listed on that street on the city's database is Crataegus crus-galli; they give the common name of thornless cockspur hawthorn. The Vancouver Trees App | UBC Botanical Garden mentions that there is a thornless selection of that species. The species is supposed to have "shiny, dark green blight-resistant leaves", so seems likely.

    For the hawthorn vs crab-apple question, both are edible - you could always eat into one to see what the seeds are like.

    Again, I don't have the exact location, but these trees on Euclid (google street view) could be in the running - it would be more likely to see hawthorns as street trees than red chokeberries (no Aronia are on the database listing). As well, the leaf margins match the hawthorns shown in a google search.

    They are located between Joyce St & Tyne Street.

    It looks like Crataegus x prunifolia.

    Crataegus prunifolia should be the thorniest of the hawthorns, with long thorns on branches.

    Good - that's the block in the google link, and the block I was looking at on the database.
