I'm a simple fellow. I went to the franchise pages on BB-Ref for all 32 extant MLB teams. I gleefully copied and pasted more than a century of W-L records into an Excel file. Man, I need a life. I found myself with 2744 seasons to play with. Which would be simply loads and loads of fun - but even I must acknowledge that the 11 years it took for the 1916 St Louis Cardinals to go from 90 losses to 90 wins is of very little relevance to our current issue.
So I sadly tossed aside all the seasons prior to the Jays' own entrance on the scene in 1977. Partially for that reason, but also because 1977 was the very first season of the modern free agency era. Free agency has obviously changed the team building process in a fundamental way, and it was seen to have done so immediately (there was this guy named Reggie, he'd been a free agent, there was a World Series that year.)
We're still left with 1276 seasons to play with. How many of those teams played at a 90 loss clip? Lots and lots. Since 1977, we have 308 seasons at a .444 winning percentage or worse. That might be a decent sample size. Alas, 50 of those seasons are still waiting for a 90 win season to end their time in purgatory. Of the other 258 seasons, here's how many years had to go by before the team reached the sunny, uplit plains of Genuine Goodness.

Happily, since 1977 every team had played at a 90 loss clip and every team has played at a 90 win clip. So here's how often each team has lost 90 games, and the number of seasons between each 90 loss season and that team's next 90 win season. (Again, all based on winning percentages.) At this moment, more than half the teams in the majors are still looking for that next 90 win season to wash away the taste of that last 90 loss season. I have used a dash to indicate those 90 loss seasons below, as I can't seem to find a symbol on my keyboard to represent infinity. Teams often put several 90 loss seasons together in groups of assorted lengths - I have marked off each group with square brackets.

I hope we're not too messianic
Or a trifle too Satanic
We just love to play the blues
