Hi
1. Yes. See:
Temporary Importation
The vehicles are entering temporarily with:
visitors, for a period of 12 months or less; temporary residents such as students studying at an institution for their studies in Canada; or individuals with valid work permits for a period of 36 months or less;
diplomats, if authorization has been granted in writing from Foreign Affairs and International Trade Canada, for the duration of the posting in Canada;
visiting forces personnel, for the duration of their assignment in Canada; and
U.S. pre-clearance personnel and their dependents for the duration of the U.S. officer's posting in Canada.
Note: A vehicle imported temporarily under one of these conditions cannot be sold or otherwise disposed of while in Canada, and cannot remain in Canada longer than the time limit listed on the person's work permit, student visa, or other Canada Border Service Agency (CBSA) or immigration documents. Once the time limit has passed, the vehicle no longer qualifies for temporary entry and must be exported. If the temporary status of the person importing the vehicle changes while in Canada, the vehicle must be permanently imported, if it qualifies, or exported.
