Justin Trudeau's election win has given Canadian pot stocks a boost with his promise to legalize recreational cannabis expected to give a boost to the nation's nascent medical marijuana industry.

Share prices for cannabis producers jumped an average of five to 10 per cent in relatively high volume trading early in the day yesterday.

The companies already produce marijuana for medical use in Canada, and investors are betting they could quickly scale up to serve recreational pot users too, once Trudeau makes good on his promise.
