Canada's adoption of number pooling significantly relieved area code exhaustion by allowing efficient reallocation of unused numbers.
Answer: False
Explanation: This statement is false. The data indicates that Canada's lack of effective number pooling contributed to area code exhaustion by preventing the efficient reallocation of unused numbers.
The proliferation of landline phones was the primary driver for telephone number exhaustion in the 613 area code.

The Ottawa-Hull local calling area historically required ten-digit dialing for calls between the two cities.
Answer: False
Explanation: This statement is false. Due to an exchange code protection scheme, calls between Ottawa and Hull historically required only seven-digit dialing for 46 years.
The exchange code protection scheme for Ottawa-Hull reserved telephone number prefixes across both the 613 and 819 area codes to prevent conflicts.
