1. As the sole shareholder of the business, is a dissolution of my CCPC be treated as share disposed at Arm's-length? 

S4-F8-C1. Article 1.12, 

"For a loss described in ¶1.11 to qualify as a business investment loss, the disposition must be:

• to an arm's-length person; or
• deemed to have occurred under subsection 50(1)."

2. Could ABIL be deducted with an optional amount? For example, I had other source of income of $70,000 in 2019 and ABIL of $100,000. Could I choose to deduct $50,000 in 2019 and carry forward the other $50,000?

Thanks!
