The rise in the $CDN is only partly related to the interest rate increase.  Since Aug 30 the price of crude WTI has risen from $45.75 to $49.20 today (USD).... Add that to a general decline of 10% in the US dollar against the world currency basket since the start of the year and the  BOC rate increases . The $CDN rise is about right.  

Digging into the Statscan numbers it's clear GDP rise is largely from export sensitive commodities.  The rise in $CDN can easily derail that GDP growth as our exports become more costly.    Canada has about a $3 billion trade DEFICIT per month, this is nothing to be trifled with ... Mr Poloz better be a bit careful with his hawkish approach which is likely making Mr Morneau a bit nervous
