There are advantages and disadvantages to incorporating both federally and provincially. To see the differences between incorporating federally and provincially, view Provincial vs. Federal Incorporation.
As a general rule, if you plan to operate in only one province you should consider incorporating provincially, whereas if you are going to operate in more than one province you should consider incorporating federally.
Ultimately though, the decision between incorporating federally and provincially is one that only the incorporators can make. If you wish to receive legal advice based on your specific circumstances, LawDepot recommends that you contact a local attorney.
