Syntax: 'canonical' vs "canonical" (Apostrophes or Quotes) does it matter?

[ccox1]

I have been working on a site and through all the tools (Screaming Frog & Moz Bar) I've used it recognizes the canonical, but does Google? This is the only site I've worked on that has apostrophes.

rel='canonical' href='https://www.example.com'/>

It's apostrophes vs quotes. Could this error in syntax be causing the canonical not to be recognized?

rel="canonical"href="https://www.example.com"/>

Hi Charles,

You can use either of them. Google doesn't make any difference between single and double quotes.

Thanks
