Why didn’t my tulips come back?

Question

Hi. In 2017 I plants rows of tulips. They came up last year, the first year and I was very happy with them. I’ve enclosed a pic taken May 8th 2018. When the plants died I cleaned up the stems and leaves. We had a good southern Ontario winter so the weather conditions are not an issue. We are in a new subdivision and have no squirrels, nothing has dug up the flower bed.
This years spring has been cooler, rainier, don’t know if that’s the cause. I’ve enclosed a pic taken May 6th 2019, you can see the difference. I have half a dozen tulips returned of the 40 plus I planted. I don’t know if they will come back, if the soil will just kill them if I replant? If I did something to kill them. Tulips are suppose to be so easy but somehow I messed it up. Please tell me if my tulips are gone forever and why this happened.

Tulips are finicky beasts. No matter where you live, duplicating their native environment isn't always easy.
The heirloom tulips are more dependable.

Here are reasons why tulips might not return:
