The main difference in the accounting for measurement issues between IFRS and ASPE is that

guidance under ASPE is concentrated in a single area of the ASPE body of knowledge.

IFRS requires explicit disclosure of fair value amounts, whereas these disclosures under ASPE are optional.

there is no difference between accounting for measurement issues between these standards.

IFRS has a well-developed framework for measuring fair values (IFRS13), whereas ASPE does not.
