They have demonstrated the intersat links, and have launched 867 satellites to working orbits with them since last September (excluding the ones that failed to deploy). Assuming they are launching the shells in sequence, if they maintain their current rate of ~4.5 sats per day on average, they will complete the 53.2° shell by the end of the year. After this, the next in line is the 70° shell. Assuming the same launch rate, it will complete in a bit over 5 months. It doesn't need to be entirely complete for service to start, but the sats will also need a few months to drift into position before they are usable. So about this time next year, Starlink will be usable in all of Canada below the ~72° line. The remaining islands will get service about 5 months after that.
And none of that requires any of their more speculative projects to work, but just for the things they are already doing to continue at current pace.
From Space-stations, Vans, and hyper-speed-vacuum tunnels.
And even if they have 867 satellites up it's still not really good, there was a good article here recently. But that's how Elon collect's his money, make big promises deliver nothing "Big" but something that already exists.
