No doubt. Although I never liked the idea of a DMLRT as a non-grade separate, subpar replacement for a DRL North. Or as a standalone line. But what I would like to see is an extension of the legacy streetcar network north of Danforth. Perhaps with the 504/505 being extended up Broadview, split along Mortimer or Cosburn, then up to the Thorncliffe area. As well, if a steetcar could be brought up Woodbine or Coxwell, then along O'Connor to Vic Park, that'd be beneficial. The service probably wouldn't be much faster than the buses that exist now, but it would allow for upzoning and intensification. And if compounded with a realigned RH RER, I think this area of the City would be set for the future.
But since it's been noted by others that the TTC no longer builds streetcar lines for in-traffic operation, this is mostly wishful thinking.

A Summary of the TTC's Report on the Opportunities for New Streetcar Routes talks about the report re: potential extensions to our streetcar network, which in a way laid the groundwork for Transit City.
Well, the idea behind transit city was converting the busiest bus routes to ROW-rail, even if there was no pre-existing track. There are a couple extensions of the legacy network that I'd really like to see, and that I've seen on a few fantasy maps:
1)
509 Harbourfront - ROW operation - The WWLRT extension of the harbourfront streetcar is the most likely to actually be built. This has good transport value. However, I think it would be more useful if it were built along Fort York and made part of the Bremner "LRT" instead of following the existing Queens Quay, especially given the issues with the light through-put at Fleet (which the TTC has noted and suggested).
2)
512 St. Clair - ROW operation - a St. Clair West streetcar extension is on the books for an extension at least to Jane, but I'd like to see it continued along Dundas to reach Kipling station. An EA was done for this. This would help continue the redevelopment of Stockyards further west. There is limited transport value in this, but given the 6-points redevelopment and all the retail and development at Islington and along dundas, this would be help support TOD and intensification.
3)
505 Dundas - Mixed traffic - A Dundas streetcar northern extension through the Junction to reach St. Clair - The Dundas streetcar used to reach this far north. This would support all the trendy new development in the Junction, and would allow operational flexibility (and significantly reduce deadheading) for the St. Clair streetcar line. The only caveat is that the Junction bus that this replaces isn't the busiest.
4)
29 Dufferin - Mixed traffic - I've seen this on fantasy maps, where the TTC's busiest bus route is replaced with a streetcar running from the Eglinton LRT's dufferin station down to Bloor and then through to downtown. This would fix the issue of forcing dufferin bus users to switch modes at bloor. Although still in mixed-traffic, this would be an improvement in comfort and capacity for what is currently one of the TTC's busiest and most uncomfortable routes.
5)
80 Queensway - ROW operation - This is a bit of a fantasy, but given how the Queensway has been identified in the Official Plan as a transport corridor, and as an Avenue meant for mid-rise development, it makes sense that it would have higher order transit to service it. Some ROW track already exists on the Queensway, continuing along all the way to Sherway gardens would support intensification and would create TOD in what I believe is one of Toronto's next big development corridors. This proposal would do better if it could connect to a DRL station around exhibition. This proposal is more axed around development than a transport need (leading rather than lagging development), given how little ridership the (admittedly infrequent) 80 bus has.
6)
65 Parliament - Mixed traffic - Changing this bus to a streetcar would require the least amount of track of any proposal. It could also connect to a DRL station.
7)
63 Ossington - Mixed traffic - Replacing this with a streetcar would require very little track, and the platform could easily be modified to handle streetcars.
8)
502 Kingston road - Mixed traffic - I'd like to see this brought up Victoria Park Avenue to the Danforth subway instead of terminating at Bingham loop
