[Tex/LaTex] Bad looking table of contents (on entire page)

page-breakingtable of contentsvertical alignment

\documentclass[12pt,a4paper]{mwrep}
\usepackage{polski}
\usepackage[cp1250]{inputenc}
\usepackage{indentfirst}

\frenchspacing
\linespread{1.3}
\author{Me}
\title{My title}
\begin{document}

\tableofcontents
    \pagebreak

\chapter{Chapter1}
\section{Section Blah}
Blah blah blah
\section{Section Xaxa}
Xaxa xaxa xaxa
\end{document}

That is my doc. When I use documentclass mwrep I got table of contents that is on entire page (even if there are 2 sections in one chapter). But when I use article, table of contents looks fine. How can I get article's look in mwrep?

EDIT:
You are right that chapter won't work with article. What I mean is that I want ToC to look like in article. It would be better to ask how can I get report's look in mwrep.

'mwrep' is supposed to be report class adjusted to Polish typography. How did I get it? I just typed \documentclass[12pt,a4paper]{mwrep} and LEd downloaded it.

EDIT 2:
Look at the difference between mwrep and report here: http://min.us/mdHsA6D and here: http://min.us/mdHsA6D#2

Simply remove \pagebreak. See \pagebreak vs \newpage for details.

EDIT: To clarify: \chapter internally uses at least one \clearpage, which (for one-column mode) essentially is \newpage plus typesetting left-over floats.
