What Canada publishes
The lotteries here do not all publish the same thing, so these pages do not all claim the same thing. Ontario prints a complete prize plan for every ticket — odds, payout and the whole prize ladder — but keeps unclaimed counts off its public pages. Western Canada publishes how many top prizes are left but no per-game odds. Neither publishes enough for a verdict on which ticket to buy, so none is ranked here.
