On Miktex your example with apa doesn't work due to two reasons:
- There is the language mapping commands missing which loads an
xxx-apa.lbx which contains some apa specific settings.
- You are using
canadian as language and the necessary canadian-apa.lbx doesn't exist here.
To solve 1. I used the following example (test.bib is the name of my bib-files for tests):
\documentclass{article}
\usepackage[canadian]{babel}
\usepackage{csquotes}
\usepackage[style=apa,backend=biber]{biblatex}
\DeclareLanguageMapping{canadian}{canadian-apa}
\addbibresource{test.bib}
\begin{document}
This statement is true \parencite[5-8]{Ref}.
\printbibliography
\end{document}
To solve 2. I used one existing xxx-apa.lbx (e.g. british-apa.lbx or american-apa.lbx I have no idea which is better suited as starting point) and made a copy called canadian-apa.lbx. Then I changed in the file in two places the language to "canadian":
- In the first line:
\ProvidesFile{canadian-apa.lbx}
- In
\DefineBibliographyExtras{canadian}...
and stored the file in a place where latex can find it.
An alternative way is to use e.g. the language american for the bibliography:
\documentclass{article}
\usepackage[canadian]{babel}
\usepackage{csquotes}
\usepackage[style=apa,backend=biber,language=american]{biblatex}
\DeclareLanguageMapping{american}{american-apa}
\addbibresource{test.bib}
\begin{document}
This statement is true \parencite[5-8]{Ref}.
\printbibliography
\end{document}
This problem is due to biblatex-apa's (apa.bbx's) apaauthor name format; you might want to notify the author of this small bug.
The string and others in the author list sets ifmorenames to true. apaauthor checks for this case whenever a name is printed, not just at the very end of the list; consequently it prints the andothers string ("et al.") after each name.
The fix is to add the following lines to your preamble.
\DeclareNameFormat{apaauthor}{%
\ifthenelse{\value{listcount}=\maxprtauth\AND\value{listcount}<\value{listtotal}}
{\addcomma\addspace\ldots\addspace}
{\ifthenelse{\value{listcount}>\maxprtauth\AND\value{listcount}<\value{listtotal}}
{}
{\ifthenelse{\iffieldequalstr{doubtfulauthor}{true}}
{\mkbibbrackets{\usebibmacro{name:apa:last-first}{#1}{#3}{#4}{#5}{#7}?}}
{\usebibmacro{name:apa:last-first}{#1}{#3}{#4}{#5}{#7}}}}%
\ifthenelse{\value{listcount}=\value{listtotal}}% this test is new
{\ifmorenames{\andothersdelim\bibstring{andothers}}{}}{}}
The MWE
\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}
@Article{boker2011,

Spiegel, M. and Brick, T. and Spies, J. and Estabrook,

equation modeling framework},

Volume = {76},

}
\documentclass{apa6}
\usepackage[american]{babel}
\usepackage{csquotes}
\usepackage[style=apa,maxnames=999,sortcites=true,sorting=nyt,apabackref=true,backend=biber]{biblatex}
\DeclareLanguageMapping{american}{american-apa}
\addbibresource{\jobname.bib}
\addbibresource{biblatex-examples.bib}
\DeclareNameFormat{apaauthor}{%

\ifthenelse{\value{listcount}=\value{listtotal}}
{\ifmorenames{\andothersdelim\bibstring{andothers}}{}}{}}
\shorttitle{IFA}
\begin{document}
OpenMx \parencite{boker2011,aksin,wilde,murray}
\printbibliography
\end{document}
then yields
Update 2013-10: This has been corrected in biblatex-apa version 6.4 according to a comment below the question from user PLK.
