Side by side

Assessed valueOakvilleMississaugaDifference
$300,000$2,504$3,102$598

$1,000,000$8,346$10,339$1,992

Assessed value, not market price. Ontario assessments still reference 2016 valuations, and the two places may sit at different distances from current market value — which is why a rate gap is not the same as a bill gap for comparable houses.

Where the difference comes from

Both are towns inside a county or region: Oakville in Halton Region and Mississauga in Peel Region, so part of the gap is a county decision neither town council controls.

Which is cheaper, Oakville or Mississauga?

Oakville, on rate. 0.83% against 1.03% means $996 less per year on a $500,000 assessment. Whether it is cheaper for the same house depends on how each place assesses it, which the rate alone does not tell you.
