Maybe the LE didn't want to take any chances while waiting for DNA results so they did the blood sample. He is from Canada after all and if he was a flight risk they had the blood sample in their back pocket to use against him. I can see them wanting to wait for the DNA result because of it being precise, but the blood could be a 'just in case' needed.
Dry Blood can be used to get a blood type.
In 1915 the Italian scientist Leone Lattes developed a simple method for determining the blood type of a dried bloodstain.
