The 3% statistic is fairly misleading. Canada has adopted the one-dose first regiment just like the UK. Which means that there is a 4 month difference between 1st and 2nd shot. The rationale was that it would overall save more lives as 1 dose is ~80% effective at preventing hospitalizations/deaths compared to ~95% for two doses. So you vaccinate double the number of people with one dose rather than half the amount with both doses and you save more lives. This was a strategic decision as Canada does not have the vaccination production, unlike the US which has prevented exporting of vaccines.

In Ontario we have 42.5% of all adults with 1 dose. In Ontario we expect ~80% of the population to have 1 dose by June 20th[1]. Which I believe is a really promising statistic, and based on current vaccination trajectory we will meet that date. The 4 month dose stretch is expected to be shrunk to a lot lower once supply has increased sufficiently and most people have 1 dose.

The increasing restrictions was unfortunate but very necessary. In Ontario at least hospitalizations and ICU capacity was getting out of hand at a faster pace than Ontario has seen throughout the pandemic. These numbers spiked in part because the lack of vaccine supply in the early days of vaccinations. Our importing of vaccines was incredibly slow at the beginning of the pandemic, mostly because we had to import from other nations which are already scrounging for vaccines. Now the pace has stepped up dramatically, based on our current jabs in arms per capita we are ~42 days behind USA[2]. Which is not that bad considering Canada has no vaccine production capacity. Excluding micronations we are ranked ~16th in the world.
