Quantities

Round off seven-digit or greater numbers when possible. Use words for million instead of writing out full numerals.
Example: The GTA is home to 6.2 million people (not 6,200,500, 6.21 million, or six-point-two million).

Use numerals when referring to monetary values.
Example: The university received $1 million from BMO Financial Group in 2004 to support the North Oshawa Library.

Keep decimals to two places unless greater precision is required.
Example: The building is 12.25 metres tall (not 12.254 metres).
